Replacing a muffler on a VAZ 2115 is not at all as simple as some people think. This will require time and a lot of money. But you can always independently carry out such a pleasant procedure as replacing the muffler of a VAZ 2115. The owner himself will decide what type of this part to install and will monitor the process with his own eyes. The muffler is one of the car parts that attracts the most attention. Although it is located under the car, being the main element of the exhaust gas cleaning system, a lot of effort and time is devoted to tuning it. It’s worth looking at several successful replacements on domestic cars, and everything becomes clear. An attractive muffler is the calling card of the entire car.
But the muffler performs not only functions that are responsible for an attractive appearance. The roar and power emitted by a sports car are no less impressive and attract the attention of many. So:
- A good muffler increases the power of a car engine several times.
- A faulty muffler not only prevents the engine from breathing normally, but also forces others to cover their ears tightly when the owner drives his car.
Exhaust system connecting parts
- the sealing gasket serves to connect the manifold and the exhaust pipe;
- a movable hinge connects the converter flange and the exhaust pipe;
- the metallographic ring is located between the flanges;
- the connecting parts between the muffler pipes are a clamp with flared ends and conical rings;
- the exhaust pipe is secured with DISPOSABLE nuts to the studs of the exhaust manifold and to the walls of the bracket.
Mufflers and pipes are a single system, and if they break down, the entire muffler device must be replaced with new ones.

Muffler mount
The muffler hangs on the car using the muffler suspension cushion (5), and the components of the muffler are connected to each other by gaskets, O-rings, and clamps.
The exhaust system of the VAZ 2114 serves to remove fuel combustion products from the engine unit. There are practically no special features in the design of the channels: it is the same as that of the entire VAZ family. Nevertheless, it is worth discussing some details, for example, how to tune the exhaust system of a VAZ or replace old structural elements with new ones.

System functions and properties
In addition to removing exhaust gases, the exhaust system of the VAZ 2114 weakens the impact of sound vibrations that the engine emits during operation. The engine creates a lot of noise, and only thanks to the exhaust pipes can it be muffled. The design of the unit consists of the following main parts:
- muffler for VAZ main;
- secondary muffler pipe;
- neutralizer (only in injection engine models);
- collector pipe;
- exhaust pipe;
- corrugation;
- resonator;
To maintain environmental standards, a catalytic converter was installed in engines with fuel injection through an injector - a device that helps reduce emissions into the atmosphere. The catalyst allows you to burn up to 95% of the fuel that enters the combustion chamber, thereby reducing the amount of combustion products and increasing engine productivity. Thanks to a set of sensors through the computer in the car, the neutralizer can regulate the amount of toxic substances in the exhaust gases. But at the moment this design is an outdated option and is practically not used in modern cars.
What to choose?
Stinger exhaust systems
There are several options for muffling devices that can be used as a replacement for the old element on the VAZ 2114.
- From the factory, VAZ vehicles are equipped with an aluminum muffler, the service life of which is up to 6 years. Inexpensive, fairly reliable solution.
- More expensive variations made of heat-resistant stainless steel. They cost more than factory ones, but are distinguished by reliability and an extended service life of up to 10-15 years.
Unfortunately, it is not uncommon that replacing a given device does not give the expected result, because instead of the expected high-quality stainless steel element, buyers are faced with counterfeits. They are made from ordinary low grade black iron. The service life of such products is no more than a year.
To give the appearance of expensive products, low-quality mufflers are coated with special paints. Therefore, we recommend purchasing parts from trusted, certified auto parts stores.
Common problems
The exhaust system of the VAZ 2115 and 2114 has one significant flaw - terrible anti-corrosion protection. Because of this, burnouts often form throughout the entire structure. This flaw has become a nightmare for inexperienced drivers. The moisture that accumulates inside the pipes destroys the metal, causing damage to the exhaust system. Another type of damage is ruptures of suspensions and channels.
This effect occurs when the catalyst fails and fuel droplets enter the system channels. When exposed to high temperatures, they ignite, which leads to fires and explosions inside the pipes.
Repairs after such damage are possible, but it makes no sense to “patch holes” by welding. Budget repair options will not work. You can replace individual parts of the assembly one by one, but this will bring little benefit. A complete redesign of the system and installation of new components will be required. But choosing the right parts is difficult. You can install pipes from a sports kit, but this will have almost no effect on the performance of the car. Therefore, the next task is to select a suitable set of pipes for upgrading the unit.
Replacement options
If you want to ensure a minimum of problems with the gas exhaust system in the future, look for stainless steel products similar to factory ones, since the exhaust pipe circuit has poor anti-corrosion protection. The shelf life of the structure will depend on the quality of materials, so stainless steel will be the most profitable purchase. To select suitable components, focus on the diameter of the old pipes.
For new steel components, do not forget to purchase an additional metal-graphite sealing ring, and also update the VAZ muffler. A rubber gasket under a stainless steel system is also useful.
Why does a sports exhaust system not make sense for the VAZ 2114? There is information that special pipes and mufflers that provide direct exhaust exit can increase engine performance by 10-15%. This effect can only be observed in cars whose engines have at least 200 hp. With. power. For the sports update to be profitable, the engine power will also need to be increased. So this type of tuning is suitable for those drivers who want their classic 2114 to become a car for racing or high-speed driving on the highway.
A few words about choosing new exhaust system parts
The car manufacturer recommends installing parts from AvtoVAZAgregat.
Its cost starts from 2300 rubles. There are cheaper parts from Chinese companies. But one cannot expect a long service life from them. Products made of aluminized steel have proven themselves well. Their service life ranges from 3 to 6 years, while ordinary ferrous metal lasts one year. Stainless steel parts also serve well, but they are unique and expensive.
The exhaust system of a car consists of certain elements. Sometimes some of its parts fail and require replacement. 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 you are pursuing, as well as on your financial condition and the availability of a particular amount of money. But we will still try to help you. In this article I will tell you about which manufacturer of exhaust system parts you should choose in a given situation and why.
The exhaust system consists of a receiving pipe 3, an additional and main mufflers (additional - 5, main - 7). . The exhaust manifold and exhaust 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 lies in the exhaust manifold and the exhaust pipe. Most cars have a downpipe with an oxygen sensor, the so-called lambda probe. They also install an additional three-component neutralizer. The mufflers and neutralizer are non-separable units. When they break down, they cannot be repaired but require replacement. 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 exhaust pipe is attached to the exhaust manifold with four studs.
The Internet space is filled with a lot of materials on the topic of independent production of tuning VAZ exhaust systems. Exhaust system VAZ 2114 tuning
. Someone claims that with the help of proper installation of these systems, you can add a couple of horsepower to your car. Some people argue with these statements. However, the truth is somewhere in the middle. And in order to comprehend it, it is necessary to understand very clearly the functional purpose and operating system of the exhaust system. This is what we will do. And only then will we determine what effect it can have on engine power in reality. The result of our work, conversation or lesson (whichever is more convenient for you) will be the answer to the question: how to properly modify the exhaust system and get an increase in power.
PERFORMANCE ORDER 1. First you need to unscrew the bolts securing the clamp. After which it can be removed. Then, you should unscrew the muffler pipe for VAZ 21008, VAZ 2109, VAZ 21099 from the resonator pipe. Now remove the O-ring. 2. Lift the muffler up slightly. This will allow you to detach the cushion from the muffler bracket. Perform the same manipulations with the cushions from the other brackets and remove the muffler for the Lada Samara. 3. Then we begin the reverse steps. Now you can easily install the muffler in the reverse order of removal.
This installation is called a catalyst. It is sometimes called a variable catalyst or a triple-acting catalyst. However, all these names do not allow us to fully understand the principle of its operation. It's worth explaining. Its triple effect lies in the fact that it is able to destroy three harmful components of exhaust gases. Thanks to the work of the catalyst, a chemical reaction occurs that helps change 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 chemical processes. The presence of high temperature plays an important role here.
Installation and dismantling
Before installation, we disassemble the old system:
- Using a metal brush, we clean the 2 bolts that secure the clamp between the muffler and the resonator.
- Lubricate the fastening nuts with WD-shkoy, machine oil or rust remover.
- Take a 13mm wrench and tighten the nuts. If this does not work out, cut it with a grinder.
- Next, remove the clamp itself and take out the sealing ring.
- We disconnect the muffler from the resonator, dismantle the VAZ 2114 muffler itself.
- We unscrew the fastenings of the remaining parts and remove them.
- Assembly is carried out in reverse order. If you have not encountered such work before, it is better to take your car to a service center to replace the exhaust system.
The VAZ 2114 muffler can be replaced independently. Just repeat steps 1-5. The resonator is replaced after dismantling the muffler.
The exhaust system of the VAZ 2114 is a complete problem. The presence of serious design flaws makes itself felt very often: either a breakdown will occur, or the pipes will rust.
The exhaust on a VAZ is easier to replace than to repair.
For urban conditions, expensive tuning does not make sense, so it is worth looking for a more reliable analogue, for example, a stainless steel exhaust system kit.
VAZ cars of the 14th and 15th models are still in demand among Russian drivers today. The machines are easy to use, do not require vigilant attention and rarely require repairs. However, they also have a “sore spot” - the mufflers. Therefore, VAZ 2114/2115 owners need to be prepared for the fact that sooner or later they will have to repair or replace the silencer on their car.
Malfunctions
- Various mechanical damage;
- Burnout of asbestos gasket;
- Fatigue and wear of the metal and, as a result, burnout;
- Defects at the joints;
- Cracks.
Considering the above, first of all, the driver must determine the source of infection and work out a schematic way to eliminate it. Let's imagine that the muffler on your car has burned out.
, this is the most common phenomenon on many cars and the VAZ 2115 is no exception.
- We must drive the car onto a viewing hole or a stationary overpass;
- We turn off the engine, squeeze the handbrake, wedge the wheels with boots or put it in first gear, you can choose any option;
- Let the exhaust system cool down a little, as it heats up under the influence of exhaust gases. You can easily burn your fingers. We always carry out all work wearing gloves.
- After making sure that the pipes have cooled down, using capes we unscrew the connecting clamps between the muffler and the resonator, otherwise known as the secondary muffler.
- From the rubber clamp-holder, remove the hook with which it secures the muffler to the bottom of the car;
- There will be an O-ring between the connections, be careful not to damage or lose it. Carry out visual diagnostics and replace with a new one if necessary. As a rule, the negative impact affects a short service life;
- Having removed the muffler, we put it aside so that it does not interfere with the process.
- We pre-lubricate the new ring with heat-resistant sealant, in this way we extend the service life;
- Install the system components in reverse order.
- After installation, be sure to start the engine and test the system. Pay attention to ensure that there are no gas leaks, otherwise your work will be down the drain.
- If everything is fine, you can continue on your way. If not, eliminate the shortcomings.
Schematically the exhaust system looks like this:
A flow of gases emerges from the combustion chamber through the exhaust manifold, exhaust pipe, neutralizer, resonator, and the muffler itself.
Burnout of the gasket can also be a weak point or “sore”
between the cylinder head and the exhaust manifold. Despite the tight pressure around the perimeter with the help of four stud bolts. The asbestos gasket still burns out, and the engine emits an unpleasant and loud sound.
Modern cars, including the VAZ 2115, use a neutralizer to significantly reduce emissions into the atmosphere, these are oxides of nitrogen, carbon, and hydrocarbons. Structurally, it consists of two parts with catalysts made of platinum and palladium. Passing through these plates, gases react, resulting in a low-toxic oxide, the harmfulness of which to the environment is minimal. According to experts, purification is about 85-95%.
What is a car muffler for?
Regardless of the make and year of manufacture of the car, all its systems serve one purpose - to ensure stable operation of the engine and movement. The exhaust system may seem insignificant compared to systems such as the brakes or fuel. However, it is the vehicle's exhaust system that has the most direct impact on engine performance.
The muffler is an integral part of the exhaust system . Its main purpose is to remove exhaust gases outside the car. In addition, the part also serves to reduce noise, since residual fuel can burn in the exhaust system pipes.
The pipe comes out from the rear left side of the car
How to attach
The muffler on the VAZ 2114/2115 is attached to the car body. To ensure that the pipe is securely fixed and does not vibrate during movement, two fastening methods are used:
on rubber suspensions.
Bolts and nuts for fastening the muffler pipes are made of special heat-resistant alloys
The muffler is attached directly to the exhaust manifold with bolted connections, which guarantee complete tightness of the joints. The middle part is also fixed with bolts and nuts. And the resonator and exhaust pipe are suspended on special hooks on the bottom with elastic bands. These suspensions are easy to remove and put on, but at the same time provide rigidity even when driving on uneven roads.
Schematic design of the exhaust system on a VAZ 2114/2115
The gas exhaust system of the VAZ 2114/2115 consists of several parts. Connecting to each other in series, all parts ultimately serve one purpose - reducing noise and removing exhaust emissions outside the body.
Reasons for part failure
The muffler is affected by several different factors that can lead to failure, these are:
- Atmospheric precipitation, dirt. Precipitation means the occurrence of rain and snow. A mass that periodically falls on a hot pipe causes temperature changes, destroying the strength of the metal. Unfortunately, it will not be possible to protect the muffler in any way; moisture will in any case affect the metal. A smart solution would be to avoid driving through deep puddles and drive slowly on contaminated sections of the road. If the muffler and pipe are dirty, it is necessary to clean it with water (you can use a pressure jet from a hose). After cleaning, it is recommended to start the engine so that any water that has entered the muffler evaporates.
- Condensate. When the unit is idle for a long time, condensation forms in the muffler, causing a corrosive process. This leads to inevitable destruction of the internal parts of the muffler. This happens extremely rarely, but before the trip it is recommended to increase the operating speed by pressing the accelerator several times. The flow of exhaust gases removes moisture from the silencer.
- Chemical influence. As a result of the release of exhaust gas, a lot of toxic chemical particles settle on the walls of the muffler, destroying the metal, and allowing road reagents to get into the muffler.
- Physical influence. Hitting stones and blows from the muffler when driving on roads also lead to a lot of damage.
The chemical and physical effect on the muffler metal is a natural process
It will not be possible to disassemble and clean the muffler, since the container cannot be opened, and only the attention and professionalism of the driver on the road will help protect it from impacts and stones. Diagnosing and eliminating minor damage at the initial stage will help to avoid serious problems in the future.
The influence of various negative factors can lead to damage to the corrugation or other parts of the muffler
Extraneous sounds in the jammer
The causes of various noises and knocks in the muffler can be:
- Fastening the muffler to wire or ties. You should not wrap the muffler on a wire, otherwise rattling and knocking will occur. Use only rubber cushions.
- Foreign objects entering through the exhaust pipe. When driving over rough terrain, deep puddles, or driving in reverse, you should not forget that the exhaust pipe is literally 20 cm from the road surface, which means that various masses and stones can be thrown into the muffler. They often knock and rattle.
- Peeling of burnt metal inside the muffler. As a result of chemical exposure, a layer of soot forms on the walls of the silencer. For this reason, over the years, rattling noises can be heard inside the muffler due to peeling metal.
- Condensation also affects the exhaust sound. Condensation forms as a result of prolonged idling while 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 signs of the malfunction disappear.
These points are possible factors influencing the exhaust sound of a muffler and are considered the most common.
Repairing and replacing the muffler on a VAZ 2114/2115 is available to every car enthusiast; the only question is confidence and time. It is easy to replace an old part with a new one if you have the tools at hand, but it is recommended to entrust the troubleshooting of the muffler to professionals. Any auto repair shop does this type of work. For little money and a short period of time, your muffler will be repaired. Remember, prevention is a reliable method of treatment!

How to replace a muffler on a VAZ 2114/2115
If you start having any problems with the muffler, it is better not to put it off for a long time. The life and health of the driver and passengers depends on how correctly the “glushak” works. In general, the replacement process itself begins with the selection of a new exhaust system kit. It is best not to save money, but to purchase an original factory one. This will delay the need for repeated replacement indefinitely.
In addition, it is recommended to change the fastening bolts during each replacement. It is necessary to choose products made from heat-resistant materials, since otherwise the bolts will quickly stick to the bottom and will be impossible to unscrew.
To ensure reliable operation, it is advisable to buy new rubber suspensions in advance.
What tools will you need?
To work you will need a simple set of tools:
two open-end wrenches for 13;
brake fluid or WD-40 lubricant;
screwdriver with a flat thin blade.
How to remove a muffler without a hole
The easiest way is to use an overpass or inspection hole - in this case, you can more conveniently crawl under the car body and carry out the necessary operations. However, drivers often do not have the opportunity to use such devices, so they use a regular jack.
To remove the “glushak” from a VAZ 2114/2115, you must:
Jack up the rear left edge of the vehicle.
Make sure the machine is stable.
Reach under the body and moisten all pipe connections and bolts with lubricant.
Wait 10–15 minutes until the liquid is absorbed.
After which you can begin to unscrew the bolted connections. If the bolts cannot be unscrewed with regular wrenches, it is recommended to cut them off with a chisel and hammer. However, you need to act extremely carefully so as not to catch the bottom.
After the pipe has been unscrewed, all that remains is to remove the part from several rubber hangers. To do this, the body is raised slightly. If the rubber band is tight, you can pry it off with a screwdriver.
The dismantled muffler is pulled out from under the car.
The muffler on the VAZ 2114/2115 is attached to the bottom with five hangers
How to install a new one and secure it correctly
Before you begin installing a new muffler, you need to clean all strategically important places under the bottom: hooks for attaching rubber bands, brackets for bolts. Install the product in the reverse order:
First, pull the muffler under the car body and position it in the position in which it will be fixed.
After this, hang the exhaust pipe and resonator on rubber hangers. Make sure that each connection is secure and the part will not fall off the hooks at the first road pothole.
Next, start tightening the nuts on the bolts. Screw it all the way, but without fanaticism, as you can break the thread.
Lower the car from the jack.
After this, it is recommended to check the performance of the VAZ. It will be enough to start the engine and rev it up a little.

Inspection
It is worthwhile to carefully inspect the muffler before starting repairs. And it would be better if the muffler was removed from the car so that it was all visible. After all, when working suspended, bending over in an inspection hole, a person quickly gets tired and may not notice all the defects. So:
- if no damage was found during the inspection, then the cause is most likely hidden in the internal resonator (in this case, you will have to arm yourself with a welding machine, cut out the resonator and replace it with a new one);
- If small holes or burnouts that were formed due to corrosion are discovered during the inspection, then a special sealant with an operating temperature range of 1000 degrees will help (before applying this sealant or, as it is also called, cold welding, you need to thoroughly clean surface);
Cold welding for mufflers
- if large holes are found that cold welding will not help, it will be necessary to use fiberglass (it can be bought at any auto store along with epoxy resin, which is used for gluing).
Corrugation repair
Corrugation, in the process of replacing the muffler on a VAZ 2115
It also happens that during the inspection process the unsuitability of the muffler corrugation is discovered. This is a flexible connection that serves to secure the exhaust pipe to the engine. There may be several reasons for the failure of this part:
- a faulty catalyst, which, if clogged, creates excess pressure that negatively affects the corrugation;
- the walls of the corrugation are corroded by exhaust gases, since the rubber mounting of the muffler was damaged or the engine mounts were damaged;
- the corrugation braid has been mechanically damaged by chemical reagents or gravel.
It is believed that the corrugation is one of the weak points of the vehicle exhaust system. First of all, experts recommend paying attention to it. Its design is an elastically tied knot that is capable of absorbing vibrations coming from the machine’s engine. The corrugation is usually replaced with a three- or two-layer braid. The corrugation installation process is not complicated:
- We cut off the old corrugation using a grinder;
- clean the cut;
- welds a new corrugation in this place;
- check the tightness;
- We cover the joints with a layer of paint (this is done to ensure a long service life).
Needless to say, this type of work requires simple skills in handling tools and welding.
Complete muffler repair (replacement of exhaust pipe)
As mentioned above, there may be several reasons for the failure of the muffler. Accordingly, its repair will involve various solutions. So, if the reason is a failure of the exhaust pipe, and exhaust gases break through under the bottom of the car, you need to arm yourself with a set of keys, a new clamp with an internal diameter of 46 mm and a new sealing gasket. First, it is recommended to watch this video, which presents a repair kit of necessary parts.
- we lift the car onto an overpass or inspection hole;
- take a 13mm socket wrench and unscrew the nut of the tie clamp (during the process you need to hold the bolt from turning with a second wrench of the same size);
- move the clamp towards the additional muffler of the system;
- take the lubricant and apply it to the junction of the exhaust pipe and the additional muffler (it will help loosen the rust and the connection will “get wet”;
- take a hammer and strike through a wooden block on the surface of the front additional muffler;
- we move it from the exhaust pipe (photo below);
Front additional muffler VAZ 2115
- use a 13mm wrench to unscrew the bolt that secures the exhaust pipe to the bracket (it is sometimes located on the gearbox);
- take a flat-blade screwdriver and bend the edges of the locking plates of the nuts that secure the exhaust pipe to the exhaust manifold;
- take a 13mm socket wrench and unscrew the nuts (there are four of them);
- with our own hands we remove the locking plates, as well as the exhaust pipe flange from the exhaust manifold studs;
Exhaust manifold of a VAZ disassembled
- we find the seal gasket under the studs;
- extract it;
Manifold seal gasket
- we bring the exhaust pipe down so that it is between the crankcase and the steering rod;
- treat the junction of the additional muffler and the exhaust pipe with a graphite-containing lubricant;
- replace the old sealing gasket and install a new one;
- install new parts;
- We assemble the exhaust pipe in the reverse order.
I would like to note that the new nuts securing the exhaust pipe to the manifold must be locked.
Complete muffler repair (replacement of main muffler)
In this case, in addition to exhaust gases breaking through under the bottom of the car, the bottom itself will rattle. You can replace a faulty main muffler with a new one, the price of which is not so expensive. So:
- the car rises onto the pit;
- the additional and main mufflers are separated;
- the hooks of the suspension straps are bent;
- detached from the brackets;
- the main muffler attached to the pillow is removed;
Dismantling the main muffler VAZ
- Installation of all parts is carried out in reverse order.

How to repair a “glushak” with your own hands
The muffler on the “fourteenth” and “fifteenth” is considered one of the most vulnerable points of the car. The fact is that due to exposure to high temperatures, the metal quickly burns out, that is, the tightness of the system is broken. Therefore, the part must be changed as soon as there is a suspicion that it is not working.
Reasons for failure
Most often, mufflers “burn out” - that is, due to hot exhaust, the metal inside the housing begins to thin out, which ultimately leads to the appearance of holes. However, this is not the only reason why the silencer may fail:
using a homemade device - handicraft products do not differ in quality and long service life;
mechanical shocks from uneven roads - dents and deformations of the pipe also lead to loss of tightness;
Rust and corrosion sooner or later affects even the highest quality original mufflers.
In general, all of the above factors influence service life to some extent. The car owner can easily identify all of the above faults - just drive the VAZ into the inspection hole and visually examine the muffler. In addition, when deformations, burnouts and corrosion reach their “peak”, the part will begin to make characteristic sounds when moving - gurgling, sharp pops, knocking.

Do you want to inexpensively buy and replace a muffler resonator for a VAZ 2115? "MSK Silencer" - urgent replacement of Lada 2115 resonators with a 1-year warranty. What is a muffler resonator?
The resonator is a closed metal module with perforated partitions, the main function of which is to slow down the speed and reduce the pressure of the exhaust gases.
As a result, acoustic pollution of the surrounding space is reduced. The resonator chambers are offset relative to each other, which makes it possible to level out strong gas pulsations, increasing the service life of the exhaust system and the engine as a whole.
Causes and symptoms of VAZ 2115 resonator failure
The main reason for the failure of the resonator is a heavy load on the infrastructure from the inside (high temperatures and pressure) with the influence of external factors (moisture, reagents, cold, etc.) from the outside.
Being under such a double attack, this device often fails, which requires qualified repair work. A malfunction of the muffler resonator can be determined by the following symptoms:
- increased noise when the engine is running;
- metallic rattling in the corresponding section of the exhaust system;
- reduction in engine power due to strong pulsation of exhaust gases
We are ready to eliminate any defects by purchasing the necessary parts ourselves. As a result, you will receive a car with a fully functional muffler, the characteristics of which correspond to the standard parameters.
“Doctor Silencer” is a network of specialized service stations for professional replacement of VAZ 2115 resonators. Service stations are located in all districts of St. Petersburg.
Signs of a resonator malfunction: decreased engine power, unusual sounds (popping, ringing) under the body, the smell of exhaust gases in the cabin. It is possible to repair the resonator if the areas of damage (burnouts, cracks, corrosion) are small. But more often a faulty resonator has to be replaced.

Replacing a muffler on a VAZ 2115 is not at all as simple as some people think. This will require time and a lot of money. But you can always independently carry out such a pleasant procedure as replacing the muffler of a VAZ 2115. The owner himself will decide what type of this part to install and will monitor the process with his own eyes
The muffler is one of the car parts that attracts the most attention. Although it is located under the car, being the main element of the exhaust gas cleaning system, a lot of effort and time is devoted to tuning it. It’s worth looking at a few successful replacements on domestic cars, and everything becomes clear
An attractive muffler is the calling card of the entire car.

Tuning the muffler VAZ 2115
But the muffler performs not only functions that are responsible for an attractive appearance. The roar and power emitted by a sports car are no less impressive and attract the attention of many. So:
- A good muffler increases the power of a car engine several times.
- A faulty muffler not only prevents the engine from breathing normally, but also forces others to cover their ears tightly when the owner drives his car.
