Downpipe VAZ 2114 injector 8 valves

The exhaust system of a car is made up of certain elements. Sometimes parts of it fail and need to be replaced. And then the consumer is faced with the problem of choosing a manufacturer. We cannot solve this problem for you, since each case is individual and the purchase of a particular part depends on the goals that you are pursuing, as well as on your financial condition and the presence of a certain amount Money. But we will still try to help you. In this article, I will popularly tell you about which manufacturer of exhaust system parts you should choose in a given situation and why.

The exhaust system consists of a front pipe 3, additional and main mufflers (additional - 5, main - 7). . The exhaust manifold and the intake pipe mounting bracket 1 available here for valve engines of VAZ 2110 and VAZ 2111 cars can be replaced with parts from Samara. The exhaust system of the VAZ 2112 engine has a difference, it consists in the exhaust manifold and the exhaust pipe. Most cars have a downpipe with an oxygen sensor, the so-called lambdo probe. An additional three-way neutralizer is also installed in them. Mufflers and converter are non-separable units. When broken, they cannot be repaired, but must be replaced. The exhaust manifold is made of cast iron. As a rule, a metal-reinforced heat-resistant gasket is located between them and the cylinder head. The downpipe is attached to the exhaust manifold with four studs.

The Internet space is filled with a lot of materials on the topic of self-production of tuning the VAZ exhaust system. Exhaust system vaz 2114 tuning. Someone claims that with the help of a competent installation of these systems, you can add a couple of horsepower to the car. Some argue with these statements. However, the truth is somewhere in the middle. And in order to comprehend it, it is necessary to clearly understand the functional purpose and system of the exhaust system. That's what we're going to do. And only then we will determine what effect it can have on the power of the motor in reality. The result of our work with you, a conversation or a lesson (as you prefer) will be the answer to the question: how to properly refine the exhaust system and get an increase in power.

PERFORMANCE ORDER 1. For a start it is necessary to turn away bolts of fastening of a collar. After which it can be removed. Then, you should unscrew the muffler pipe vaz 21008, vaz2109, vaz 21099 from the resonator pipe. Now take out the sealing ring. 2. Slightly lift the muffler up. This will allow you to detach the cushion from the muffler bracket. Perform the same manipulations with pillows from other brackets and remove the Lada Samara muffler. 3. Then we begin the reverse actions. Now you can easily install the muffler in the reverse order of removal.

This unit is called a catalyst. It is sometimes referred to as a variable speed or triple action catalyst. However, all these names do not allow us to fully understand the principle of its work. It's worth explaining. Its triple action lies in the fact that it is able to destroy three harmful components of exhaust gases. Thanks to the work of the catalyst, chemical reaction, which contributes to the change of harmful substances into harmless chemical compounds. Carbon monoxide, oxygen and nitrogen dioxide are modified. They turn into carbon dioxide, nitrogen and water. Such reactions occur due to the presence of metals such as platinum, palladium and rhodium. They have a catalytic effect in the chemical process. The presence of high temperature plays an important role here.

Mechanical blowers are one of the best tools to increase power and traction. As early as 80 years ago, they began to be used in the automotive industry. The principle of operation of the device is simple: the fuel-air mixture enters the engine cylinder and is compressed by the piston. The spark plug ignites it, causing it to explode. As a result, the piston makes translational downward movements cyclically. The larger the volume of the engine, the more the mixture enters it, and as a result, the power and traction increase.

arose new problem: put wheels 17 radius, now on high speeds practically does not slow down. I looked for information, learned from friends how to be. I came to the conclusion that it is worth putting Pilenga Sport perforated brake discs and ATE pads. At first, there were no changes. Later, when the new pads got used to the discs, I felt the difference. Yes, what! The car began to slow down five times better than before, and it’s not worth comparing with the Vazovsky ones.

Exhaust gas is one of the most important elements of modern vehicles. In order to preserve natural resources and ecology environment, the requirements for the composition of exhaust gases are becoming more stringent. To ensure their cleaning and removal, the main purpose of the exhaust gas system.

How exhaust gases are removed

To remove exhaust gases, the VAZ 2114 exhaust system was developed and installed, the diagram of which is shown in the figure.

It consists:

Bracket for fastening the receiving pipe;
Sealing gasket;
clamp;
Rubber shock absorber;
Central muffler;
Rubber shock absorber;
Clamp connecting pipes;
Converter;
Sealing ring for hinge;
Oxygen sensor;
Receiving pipe.

The output of exhaust gases occurs as follows. From the exhaust manifold, the exhaust gases enter the channel, which is called, it directs them further into the converter. From its name it becomes clear that it is intended for afterburning the remains of combustible substances in the exhaust gases.

In it, the primary blunting of exhaust noise and a decrease in turbulence occurs. The next “obstacle to gases” is the silencer resonator, in which “acoustic mirrors” reduce the noise of the exhaust gases even more. And the last step will be the central silencer. The exhaust system is made and installed in such a way that the emission of gases occurs outside the vehicle, this prevents them from entering the passenger compartment.

How is the central muffler

They are made of aluminized steel, stainless steel, ferrous metal and powder coated. The installation of straight-through sports mufflers is gaining popularity. The silencer device can be seen in the figure.

Silencer VAZ 2114 consists of:

Metal case;
heat-insulating layer;
Partition;
Pipe with perforations;
Calibrated hole (throttle);
Front pipe with perforations;
inlet pipe;
Partition in the middle part;
Exhaust pipe;
Baffle in the front of the muffler;
Back pipe with perforations;
Partition in the back;
Metal case.

It should be noted that the exhaust system of the VAZ 2115 with a carburetor engine differs from the design described above. It does not provide for the installation of a converter for the outgoing exhaust gases.

On the factors affecting the service life of the elements of the exhaust system

The elements of the exhaust system operate under the influence of mechanical, thermal and other types of loads.

The following factors have a strong influence on the service life:

Rapid heating to high temperatures, which can cause overheating of the system elements;
Frequent fluctuations in rapid heating and rapid cooling;
Vibration during operation power unit;
Susceptibility to shock and mechanical damage;
Pollution while driving in bad weather conditions;
Obtaining scratches and chips from particles of the road surface;
The occurrence of foci of corrosion both inside and outside the elements of the exhaust system;
Insufficient metal protection efficiency.

It can be stated with certainty that for most of these factors, the timing of their manifestation is easily postponed to a later time. It is worth changing the style of driving a car, periodically cleaning the exhaust system from dirt, applying a protective coating on your own, and the problems will move away by themselves.

About symptoms

As soon as there is even the slightest suspicion of problems with the exhaust tract, steps must be taken to identify and eliminate these suspicions. Driving with a faulty muffler can create problems for neighbors and traffic police.

You should be alerted by the following manifestations in the operation of the exhaust system:

The appearance of increased noise of a running motor;
The presence of exhaust odors near the car, and in some cases in the cabin;
The appearance under the bottom of the car of smoke from burnt exhaust elements;

There is no need to shelve the solution to this problem. Take a few minutes to detect and determine the breakdown. After that, a decision is made to eliminate it. There may be only two options, this is the repair of the muffler or the replacement of the VAZ 2114 muffler.

Repair or replacement

Diagnostics found one or more small cracks in the body of the resonator or the main muffler. In this case, it is not economically profitable to change them with new parts. Can . To do this, purchase a muffler repair kit: it includes rubber shock absorbers (a pipe is suspended on them) and clamps (for connecting pipe joints). They can be purchased in several types.

You can repair VAZ 2114 mufflers in the following ways:

They purchase any heat-resistant sealant and coat them with burnout slots, namely slots, and not large holes. The next step is to clean the body of dirt, paint and rust. After that, the cleaned place is degreased and the sealing layer is laid on the repaired place;
Buy a repair kit with heat-resistant tape and knitting wire. Again, the preparation of the repaired part is underway by analogy with the first method. After that, carefully wrap the body with tape and tie it with wire. The burned-out place itself is tightened during the operation of the engine;
Repair by cold welding. First of all, prepare cold welding for use. Next, you need to clean and degrease the damaged area well. After that, the damage can be repaired by welding (cold).

Of the described methods, the method using the repair kit received the most positive feedback.

For car owners who have access to electric welding, this method of muffler repair can be recommended. A patch is cut out of a sheet of metal 1.5-2 mm thick the right sizes. Apply to the place of repair and scald. Then the repair site must be treated with a protective compound. Good results are obtained by the use of semi-automatic welding in shielding gases.

How to make a replacement

Diagnostics showed that the repair will not give the expected effect, which means that you need to change the VAZ 2114 muffler. This is quite simple to do if you have a new part. The replacement operation is carried out with your own hands in the garage or even just in the yard.

You can change the muffler VAZ 2114 like this:

Unscrew the bolt on the connecting clamp and remove it together with the sealing gasket;
Release it from the suspension, disconnect from the resonator and remove;
When installing a new part, the gasket must be smeared with sealant for exhaust systems and installed in reverse order.

A few words about the choice of new exhaust system parts

The car manufacturer recommends installing parts from AvtoVAZAgregat. Its cost starts from 2300 rubles. There are cheaper parts from Chinese manufacturers and other "unknown" companies. But don't expect a long lifespan from them.

Products made of aluminized steel have proven themselves well. Their service life ranges from 3 to 6 years, while ordinary ferrous metal can withstand one year. Stainless steel parts also work well, but they are unique and expensive.

Every car exhaust system has a muffler, and for many car enthusiasts, its purpose is obvious. It will be uncomfortable to drive around the city with a loud and poisonous exhaust, and the fines for exceeding the permissible noise level and harmful emissions from the operation of the car are quite large today. When operating VAZ vehicles, the muffler is often not given due attention, although it is useful to know how to correctly diagnose the degree of wear. Timely replacement of the “glushak” is mandatory, since its malfunction can become a threat to human health and the operation of the car engine.

Silencer - purpose, device, work

An important element of the exhaust system is a muffler, the operation of a car without it is impossible. As a rule, the muffler is located at the rear of the vehicle and, together with the exhaust system, serves to remove harmful gases from the engine, bypassing the passenger compartment.

Automotive mufflers are made from stainless, aluminized and regular black steel. Stainless steel plugs are practically non-existent on sale due to their high cost and long service life (their service life is 10–15 years). Aluminized mufflers are installed on the VAZ 2114/2115. They are common in the domestic and European markets (service life 3-7 years). Regular black steel mufflers are cheap substitutes and last only a few months, so they are rarely used.

Why do you need a "muffler"

The main functions of the muffler:

reduction of noise during fuel processing;
reduction in the rate of emission of gases, their temperature.

The muffler is mounted with special rubber pads on curved metal hooks, softening vibrations from car exhaust.

All elements of the exhaust system are exposed to high temperatures, so the coating (anti-corrosion paint, mastic) that is applied to the muffler burns out. The exhaust system of the VAZ 2114/2115 is mounted under the body on the bottom of the car.

An additional muffler or, in other words, a resonator is designed to eject burnt gas into the exhaust pipe and receive the next portion.

Resonator - an important part exhaust system, it directly affects engine power. The faster the exhaust gas is removed from the resonator, the faster and more the car's power develops.

The design of the pipe consists of all the necessary elements, therefore, when withdrawing, the exhaust gas is correctly distributed throughout the entire exhaust line

The muffler on the VAZ 2114/2115 is attached to the bottom of the car with special rubber bands, clinging to the flat hooks on the side and top. Why is an elastic band used, and, for example, not a metal mount?

During the passage of exhaust gases through the exhaust pipe, vibrations increase, the muffler begins to vibrate, and if the mount is solid, then the vibration will be transmitted to the passenger compartment. The rubber muffler mount softens vibrations, therefore it is used on all cars.

In VAZ 2114/2115, the muffler is a voluminous sealed metal chamber, divided inside by various partitions. The entire flow of exhaust gas passes through the muffler sections, finally extinguished and cleaned. If we consider the muffler diagram, then on all cars it will look almost the same.

The principle of the removal of exhaust gases from the muffler of the car

Silencer replacement for VAZ 2114/2115

The failure of the muffler on the car can happen for various reasons:

mechanical damage;
the influence of atmospheric and mud precipitation;
burnout of internal elements and walls of the muffler.

Symptoms of a malfunction, most often, are manifested in an increase in the exhaust sound: the car runs very loudly, rumbles, there is an abundance of exhaust gases from under the car in the muffler area and the smell of unprocessed fuel.

How to change the "glushak" with your own hands

In many cases, the muffler cannot be repaired - its urgent replacement is required. This is not as difficult to do as it seems. You will need:

new silencer + repair kit (rubber cushions, corrugation, metal-graphite ring installed under the clamp at the junction of the pipes of the additional and main silencers);
tools;
portable lamp;
inspection hole or jack;
two hours of free time;
hands growing from the right place.

The repair kit consists of 5 rubber pads, two clamps and o-rings, gaskets

After purchasing parts, you need to make sure that they are really suitable for replacement. All fasteners, holes and bends should be checked.

If all of the above corresponds to the parameters, you can proceed to dismantle the broken muffler. After installing the car on the inspection hole, check the condition of the fasteners and connecting bolts of the clamp between the pipe of the additional muffler and the pipe of the main muffler.

How to remove the muffler

Before loosening the nuts, treat the threads with WD-40 or rust remover, wait 10 minutes.
Using a box wrench or a 13 socket, unscrew the two nuts holding the clamp.
Remove the clamp and remove the sealing ring.
Remove the rubber pads holding the muffler.
Disconnect muffler from resonator.

If you have difficulty loosening the nuts, you can use a hammer and chisel. To do this, you need to rest the chisel on the face of the nut and with sharp blows of the hammer counterclockwise try to “knock down” the thread. Otherwise, cut the bolts with a grinder.

Installing a new part

Installing a new muffler is done in the reverse order, but it is necessary to lubricate the gasket ring with high temperature sealant. This will ensure a secure and tight connection.

In the absence of a viewing hole, you can use a jack, after setting the stop under the front wheels.

Repair of the muffler VAZ 2114/2115

Before changing the muffler, it is necessary to inspect it for damage. In some cases, you can get by with minor repairs and not spend money on buying a new part. The muffler is restored to working order according to the following algorithm:

The muffler and welds are cleaned with emery cloth.
The entire part is inspected for cracks, burnouts, damage.
If a defect is found, use semi-automatic welding, weld cracks. A metal plate with a thickness of at least 1.5 millimeters can be welded to the places of burnout. Cover small cracks with high temperature sealant.

All work areas must be processed with sandpaper for a better result.

Welding is used if the muffler metal is strong enough. The seams are boiled in a thick layer to avoid background and new burnout.

Causes of part failure

The muffler is affected by several different factors that can lead to breakdown, these are:

Atmospheric precipitation, dirt. Precipitation refers to the amount of rain and snow. A mass that periodically falls on a hot pipe causes temperature drops, destroying the strength of the metal. Unfortunately, it will not be possible to protect the muffler in any way, moisture will affect the metal in any case. A smart decision would be to avoid driving through deep puddles and driving slowly on muddy sections of the road. If the muffler and the pipe are dirty, it is necessary to clean it with water (it is possible from a hose with a pressure jet). After cleaning, it is recommended to start the engine so that the water that has entered the muffler evaporates.
Condensate. During prolonged idle operation of the unit, condensation forms in the muffler, causing a corrosive process. This leads to the inevitable destruction of the internal parts of the muffler. This happens extremely rarely, but before the trip it is recommended to increase the working speed by pressing the accelerator several times. The flow of exhaust gases removes moisture from the muffler.
chemical influence. As a result of the release of exhaust gas, a lot of toxic chemical particles are deposited on the walls of the muffler, which destroy the metal, the ingress of road reagents onto the muffler.
physical influence. Stones, muffler blows while driving on the roads also lead to a lot of damage.

Chemical and physical influence on the muffler metal is a natural process. It will not be possible to disassemble and clean the muffler, since the container is not opened, and only the attention and professionalism of the driver on the road will help protect against bumps and stones. Diagnosis and repair of minor damage to initial stage help to avoid serious problems in the future.

The influence of various negative factors can lead to damage to the corrugations or other parts of the muffler

Extraneous sounds in the "muffler"

The causes of various noises and knocks in the muffler can be:

Mounting the muffler on a wire or ties. The muffler should not be wound on the wire, otherwise rattling and knocking will be provided. Use only rubber pads.
Ingress of foreign objects through the exhaust pipe. When driving over rough terrain, deep puddles, driving in reverse, do not forget that exhaust pipe is literally 20 cm from the road surface, which means that it is possible to throw various masses and stones into the muffler. They often knock and rattle.
Flaking of burnt metal inside the muffler. As a result of chemical action, a layer of soot is formed on the walls of the plug. For this reason, over the years, rattling can be heard inside the muffler due to exfoliated metal.
Condensation also affects the sound of the exhaust. Condensation is formed as a result of prolonged operation on Idling, when the engine warms up. Ringing and "gurgling" are signs of accumulated moisture in the muffler. By increasing the speed several times, the condensate comes out and the symptoms of the malfunction disappear.

These items are possible factors influencing the sound of the muffler exhaust and are considered the most common.

Repair and replacement of a muffler on a VAZ 2114/2115 is available to every car enthusiast, the only question is confidence and time. It is easy to change an old part for a new one, having tools at hand, but it is recommended to entrust the elimination of a muffler malfunction to professionals. Every auto repair shop does this kind of work. For little money and a short period, you will be repaired by a muffler. Remember, prevention is the best cure!

The main elements of the exhaust gas system of a VAZ 2114 car are: a front pipe, a converter, an additional and main muffler. The downpipe of the system is connected to the converter by means of a moving hinge. As you can see, this design has a lot in common with the VAZ 2109 exhaust system.

At the same time, in order to ensure a reliable and tight connection, a special graphite ring is installed between the flanges of both parts. It should also be noted that in order to exclude heating of the bearing part of the body, a gasket is provided above the converter, which acts as a heat-repellent screen.

At the same time, a so-called oxygen concentration sensor (Lambda Probe) is installed at the inlet to the converter. What is it for? It's simple: it is necessary for exact definition the oxygen level in the exhaust gases, the composition of which depends on the composition of the fuel mixture supplied to the engine cylinders. Thus, the information produced by the sensor is fed into the electronic engine control unit and is used to quickly adjust the amount of fuel injected into the cylinders.

As in most cars of the VAZ family, the additional and main mufflers of the VAZ 2114 exhaust system are fixed to the bottom with the help of special rubber suspensions. With their help, the vibration that occurs during the passage of exhaust gases through the mufflers is practically not transmitted to the body, which high level noise in the car.

Replacing the main silencer on a VAZ 2114

To perform work on removing the main muffler, you will need two ring wrenches for "13". We drive the car into an inspection hole and wait for some time until all elements of the exhaust system have completely cooled down.

By the way, quite often there are cases when, due to severe corrosion, it is not possible to unscrew the clamp bolts and remove it. In such situations, an angle grinder is used, with which the mounting bolts or the entire clamp are cut in parts.

After the clamp is removed and the pipes are disconnected, you can remove the main muffler. To do this, carefully holding it, we remove the rubber suspension from the brackets on the body.

Then we remove the muffler from under the car. We install a new part in the reverse order.

Do-it-yourself resonator replacement

To remove the resonator (additional muffler) you will need: two keys for "17" and two keys for "13". Before starting dismantling, it is advisable to treat all fasteners with a rust-dissolving agent. For example, it can be such a popular WD-40.

First of all, we unscrew the clamp, through which the additional muffler is connected to the main one. This process has been described in more detail above. Now we place some kind of stand under the catalytic converter, so that after disconnecting the resonator, the catalyst does not sink and is not damaged.

Now, using the keys to "17", we unscrew the bolts securing the additional muffler to the catalyst. We pull out the bolts and remove the additional muffler.

Installation of a new resonator is carried out in the following order:

1. When installing a new additional muffler, we first fix it on the side of the catalytic converter. To do this, insert the bolts and tighten their nuts for several turns of thread.

3. We put a new coupling clamp in place, after which we completely tighten the bolts securing the resonator to the catalyst.

Removal and installation of the catalyst

Work on removing a faulty catalyst can only be started after the complete cooling of this element of the exhaust system. Remember that the catalyst heats up much more than pipes and mufflers. Therefore, in order for it to cool completely, it takes more time than in the case of replacing mufflers.

Dismantling of the neutralizer is carried out in the following order:

First, unscrew the bolts that attach the catalyst to the additional muffler. We separate the pipes.

Now we unscrew the bolts securing the catalyst to the exhaust pipe of the exhaust system.

Remove bolts and spring washers. Remove the catalytic converter from under the car.

Tuning the exhaust system VAZ 2114

As practice shows, the task of absolutely any really effective tuning of the exhaust system is to reduce the resistance of the exhaust gases produced by the power unit. The modified exhaust gas system has a much lower level of resistance compared to the standard system, which significantly increases the rate of exhaust gases. In turn, this leads to an increase in engine performance and in particular to a certain increase in its power.

As a rule, the first thing that professional "tuningists" pay attention to is the intake manifold. By the way, this element is also called a "spider" for its peculiar shape. The upgraded intake manifold is installed instead of the regular one, ensuring the removal of gases from each of the working cylinders of the engine. Accordingly, the gases do not mix, but are discharged directly into the pipe.

Catalyst dismantling

In addition to installing a more advanced exhaust pipe, fans of fast driving very often resort to the complete dismantling of the catalytic converter. The motive for this decision is simple - the removal of the "obstacle" in order to increase bandwidth exhaust system. Of course, this significantly increases the exhaust toxicity indicator. However, within the framework approved by current legislation, exhaust toxicity (without a catalyst) fits perfectly. That is, the operation of a car without a catalytic converter is completely legal.

It should be noted that if the catalyst is removed, a slightly different element is installed in its place - a flame arrester. Structurally, this flame arrester is a piece of pipe of the same length and with the same fastening method as that of the catalyst. At the same time, a small wire "washcloth" is located inside the flame arrester, which eliminates the occurrence of micro-ignitions.

At the same time, in order to prevent rapid destruction due to corrosion, the body of a home-made flame arrester must be painted with a special heat-resistant anti-corrosion paint.

Unfortunately, modern industry does not produce flame arresters for domestically produced cars. That is why those wishing to improve exhaust system, make it yourself. In principle, there is nothing complicated about this - it is enough just to be able to use a cutting machine (“grinder”) and a welding machine.

Each vehicle system, regardless of its application, is of great importance for the performance of the car. The exhaust system, despite the seeming secondary in comparison with the engine, has an impact on the efficiency of the fuel combustion system. Any experts will say that the patency of the exhaust gas exhaust system is the key to the “health” of an automobile engine. And, conversely, any obstacles in the way of products that are obtained during the combustion of fuel in the engine cylinders can significantly reduce the power of the car and even stall its operation. As a result of all of the above, knowing all the features of the exhaust system is an important component of the flawless operation of the vehicle.

The exhaust system of the VAZ 2114 consists of various functional elements. Folding into a single chain, it balances the operation of the engine in optimal modes, while controlling the level of noise emitted by the power unit, the amount of harmful emissions that form during the combustion of the combustible mixture, and with the correct setting, it allows more efficient use of engine torque. On the VAZ 2114, the exhaust system consists of the following parts:

muffler vaz 2114

The exhaust gases that leave the engine cylinders have high pressure. In the process of their movement through the exhaust system, sound waves are formed that propagate faster than gases. The muffler converts the energy of sound waves into thermal energy, which makes it possible to achieve a reduction in the noise level to a predetermined value. However, with the use of a silencer, back pressure is formed in the exhaust system, leading to some decrease in the power of the power unit.

The muffler uses a number of noise reduction technologies:

Absorption of sound waves.
Interference of sound waves.
Change of flow direction.
Narrowing (expansion) of the flow.

Modern car mufflers are usually divided into three types - aluminized steel, stainless steel and sports (straight-through). VAZ mufflers, made of very durable stainless steel, are one of the most popular types.

They received such a high prevalence among car owners as a result of the simplicity of the material from which the mufflers are made, and, consequently, the relative cheapness of the device itself. This type of mufflers is actually universal, as it fits many other car brands. Moreover, wherever stainless steel mufflers are installed on a car, they effectively and reliably perform their functions.

As for fixtures made of aluminized steel, they cost a little more. However, most often, it is more profitable to install them than cheaper analogues, since the warranty period for their operation is longer by seven, or even as much as ten years. But, as a result of their high cost, these devices are made, as a rule, by individual orders.

Straight-through (sports) mufflers are mainly used in the technical refinement of the vehicle to give it additional speed characteristics. Such devices are also made of stainless steel and are used on cars for racing (sports) purposes.

stinger vaz 2114

Among the owners of VAZ cars, Stinger is known as a manufacturer of exhaust system tuning elements. The company began its work 12 years ago with the manufacture of forward flow for classic cars, today, under its own brand, Stinger produces resonators, mufflers, exhaust manifolds and related spare parts for VAZ and some foreign cars, in particular KIA, Daewoo, Gelly, Chevrolet and others .

The main advantage of the Stinger is durability. We all know that ordinary parts for the exhaust system of VAZ cars are not made from the highest quality materials, and their service life, as a rule, does not exceed four years.

The stinger is made of high quality stainless steel and powder coated. It is worth noting that with proper care, it can last two or even three times longer than usual.

The elements of the Stinger exhaust system are made of stainless steel (08 PS). Non-combustible cotton wool of foreign production was used as a filler. A special stainless mesh barrier prevents the filler from being blown out. A complete replacement of the 2114 exhaust system can add a few horsepower to the car and significantly improve dynamics, which will make it possible to leave many modern cars behind.

Owners of the VAZ 2114 can choose between several muffler options - the FSA series, the STINGER SPORT series or the MUTE series. In addition, there are various additional details, such as a connecting collar, rubber rings and decorative nozzles.

resonator vaz 2114

The resonator is an element of the exhaust system that dampens the sound waves of exhaust gases that escape from the combustion chamber. The design, shape and size of the resonator directly affect the volume of the power unit. If this element breaks down, the operation of the entire exhaust system is disrupted. The vehicle becomes noisy, and an unpleasant smell of exhaust gases enters the cabin.

The muffler resonator directly affects the power of the motor. The faster he manages to remove the burnt gas from the power unit, the faster the engine burns fuel, and, consequently, the more power. However, unfortunately, the muffler resonator on the VAZ 2114, like on any other car brands, is constantly exposed to high temperatures, as a result of which it wears out quickly.

Exhaust system malfunctions

The level of performance of the exhaust system as a whole, as well as its individual parts, is influenced by such unfavorable technological factors:

Development of external and internal corrosion.
Chips and scratches caused by small hard particles of the roadway.
Frequent pollution.
Frequent impacts, as well as mechanical damage to the muffler.
Permanent vibration during operation of the power unit.
Sharp frequent fluctuations in temperature regimes - from cooling to rapid heating.

All the factors considered to one degree or another affect the performance and safety of the exhaust unit. In case of violation of integrity, a gas flow immediately rushes into the formed fistula or fracture, which expands the emergency hole due to its pressure and speed.

And then the breakdown makes itself felt - the exhaust gases exit at the wrong point, the system starts to clap loudly and “growl”, the muffler knocks. It becomes virtually impossible to operate a car in such conditions.

Keep in mind that in addition to sharp and loud pops, defects in the 2114 exhaust system can also affect the performance of the power unit itself. Therefore, sometimes it is necessary to repair individual elements of the system, which will allow for some time to do without replacing the entire assembly as a whole.

The diagnosis of breakdowns, which precedes restoration operations, is facilitated by the fact that the appearance of defects is usually accompanied by an unpleasant strong roar and rattle under the car bottom. It remains for the car owner to carefully study the entire chain and diagnose the nature and location of the malfunction. Most often, problems occur in the following components:

exhaust repair

The entire exhaust system is a complex of welded metal elements, the repair of which will necessarily require welding. The main trouble of the muffler is the formation of through holes in the pipes and body.

There is an option to temporarily repair the damage with a special heat-resistant bandage with an epoxy composition or "cold welding". However, the service life of such patching is short.

Repair work begins with the removal of the section of the exhaust system in which the "hole" occurred. Typical places are the resonator or silencer. Regardless of the cause of the formation of a fistula, they treat it with the same method - applying patches.

For repairs, sheet metal pieces should be prepared in advance. First of all, we determine the size of the damage. Places where there is already corrosion must be removed completely by cutting them out with an angle grinder.

It is useful to treat the internal surfaces with a special anti-corrosion compound. Then we cut out a piece of sheet metal that could cover the missing area, but with some margin - 1-1.5 centimeters. Next, you should clean the place of welding and weld the patch. For work, it is desirable to use a semi-automatic welding machine, which is used for body welding. It is important that the welding seam is even and continuous. In the same way, fractures and burnouts on the nozzles are eliminated.

muffler repair

Change gaskets. In different car models, the number of sealing parts at the sealing points varies to some extent. To replace the gasket in the muffler, it is necessary to dismantle the entire exhaust system or a small section of it. Despite the small number of fasteners, the dismantling of the muffler can take hours. Before starting work, treat the fasteners with a special fluid, such as WD-40.

The process of replacing gaskets is not very difficult. Remove the old sealing material and clean the joints. The adjacent planes of the two muffler elements must be in close contact with each other. If there are small pits on the metal flanges, use a heat-resistant sealant.

We repair muffler pipes. There are many pipes in the exhaust system of a car. They are straight and curved. As a rule, burnouts occur at bending points, which occurs for several reasons:

Exhaust gases strongly affect the curved part.
When bending, the wall of the pipe becomes thinner.

To repair a large hole or crack, use a welding machine. Sometimes it is possible to avoid dismantling the muffler if it is possible to get close to the place of welding from below the car. A steel patch is welded onto the problem area or a welding seam is applied.

Not infrequently, depressurization of the system occurs at the junction of the pipe with the tank or resonator. In this case, the damaged area will have to be dismantled from the car and try to restore it. To do this, you will need: a piece of sheet metal, a metal rod or a piece of wire, a semi-automatic welding machine.

First, we remove corrosion-damaged areas and loose rust from the elements. Further, with the help of welding, the pipe is stuck to its original place. Then you should fill the holes and slots with pieces of wire or install a sheet metal patch.

muffler replacement

First of all, you should spray WD-40 on the mounting nuts of the muffler connection clamp, as they, as a rule, rust and stick strongly, as a result of which it is rather problematic to unscrew such a thread.
Next, using a 13 wrench, unscrew the clamp nuts. Use the ratchet handle and head to get things done quickly and conveniently.
It is not necessary to unscrew the second nut to the end, since the clamp can be pushed back.
We unbend the edges of the pipe with a flat screwdriver.
Next, knock down the muffler with a hammer from the junction towards the exhaust pipe.
At two points where the muffler is suspended, we take out the cotter pins with pliers.
On last step dismantling, it is necessary to take the muffler out, for which we turn and unscrew the pipe in different directions.
Now install the new muffler in reverse order.

resonator repair

When the outer wall of the resonator burns out, the part can be restored for a while. To do this, thin and rusty metal is cut out in the problem area. It is desirable to cut a simple rectangular shape to make it easier to prepare a patch of the same size. Now we apply a patch to the resonator and scald around the perimeter.

catalytic converter repair

If the catalytic converter leaks, it is necessary to replace this element. With the help of an assistant, it is not uncommon to carry out a replacement without dismantling the muffler, for which you should carefully cut out the catalyst with a grinder. Next, we apply a new element to the pipe and weld. It is important to choose the right changing part, and also not to make a mistake while working with a grinder.
