Lada 2114 › Logbook › Replacing the resonator

In the terminology of drivers and car mechanics, the word muffler often means the entire complex of chambers and pipes that are included in the exhaust system of a modern vehicle, hence the name - muffler resonator. Replacing a faulty resonator yourself is a rather labor-intensive undertaking, but quite doable at home. It is worth noting that due to the design features of the resonator, it cannot be repaired, so the only way out in the event of a breakdown is to replace it with a new one. More on this later in the article.

Why is a muffler resonator needed in a car?

After ignition occurs, gases enter the intake manifold, and then into the muffler pipes.
The resonator performs the function of reducing vehicle noise. The second, but no less important function is environmental. The resonator acts as a filter element. The operation of the exhaust system and its sound directly depend on the type, shape and size of the resonator. Failure of this part can lead to loud noise when the car engine is running, especially when the accelerator pedal is actively used, increasing engine speed.

In addition, the unpleasant smell of exhaust gases will begin to penetrate into the cabin.

Resonator device

Many car enthusiasts call the resonator a small muffler. This is explained by external features, namely the similarity with the main muffler.

Structurally, the resonator consists of a large number of layers, each of which has its own purpose. Gas entering the resonator passes through the reflectors. Thus, hot gas particles are quenched against them, dividing into two streams. In addition, the inside of the resonator is divided into two sections. A special mesh is used for this. It divides the frequency of vibrations and dampens them using friction

It is important that there is uniform pressure distribution inside the resonator so that resistance does not arise. This will ensure stable operation of the internal combustion engine, maintaining the required speed level

Types of resonators

There are two types of resonators - for two-stroke or four-stroke engines. Photo: Minsk.deal.by

There is an opinion that a resonator installed on a four-stroke engine does not provide any benefit, but only reduces the power and overall efficiency of the engine. If you remove the resonator from the exhaust system of a four-stroke engine, its power will increase by up to 15 percent. However, for the environment, such a solution will not be an advantage at all.

Installing a resonator on the exhaust system of a two-stroke engine, on the contrary, has a positive effect. Without a resonator, such an engine will consume more fuel.

What it is

Often in auto repair shops, corrugation is mentioned as the cause of a malfunction in the exhaust system of a car. So what is a muffler corrugation? In appearance, it resembles an elastic tube with metal weaving in the form of a multilayer mesh. This flexible part is an integral part of the exhaust system of any modern car. It is an intermediate link between the exhaust pipe and the exhaust pipe of the muffler.

Unfortunately, the muffler corrugation is located in such a place that after hitting an obstacle that hits it, the corrugation may need to be replaced. Also, the need to replace it arises due to natural wear and tear after a certain number of operating cycles.

Replacing the resonator yourself

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

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

Now, using keys “17”, unscrew the bolts securing the additional muffler to the catalyst. 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, first fix it on the catalytic converter side. To do this, insert the bolts and tighten the nuts with several turns of thread.

2. Next, we connect the main muffler with the additional one. At the same time, we install a new graphite ring-spacer between them. It is imperative to check the tightness of the graphite gasket.

3. Place a new clamp at the connection point, and then completely tighten the bolts securing the resonator to the catalyst.

Pilenga spare parts

A new problem has arisen: I installed 17-radius wheels, and now it hardly slows down at high speeds. I looked for information, found out from friends what to do. I came to the conclusion that it is worth installing 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 brake five times better than before, and it’s not worth comparing with the Vazovskys.

Hello dear readers! Today we will talk about replacing the muffler of the VAZ-2114 hatchback. It is worth noting that the failure of the muffler is one of the most common problems that arise among owners of this car.

Let us recall that the main purpose of a car muffler is to reduce toxicity, temperature and noise of the car engine. Today, there are three main types of parts:

• stainless steel,
• made of aluminum,
• sports modifications.

The fourteenth Zhiguli model uses a stainless steel muffler.

How to repair a silencer 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 these 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.

Why is the muffler knocking?

This part on the VAZ 2114/2115 can make knocking noises only in two cases:

When moving, it touches the gas tank housing.

In any case, it is necessary to immediately take measures to eliminate this malfunction. Most often, the problem lies in severe wear of the rubber suspensions. It is enough to change them and the muffler will again return to its normal position under the bottom of the car.

In some cases, the silencer begins to knock when its elements have been installed incorrectly - for example, after replacing the resonator or exhaust pipe. In this case, you will need to double-check that all fasteners and gaskets are installed correctly.

What to do if the plug is clogged

During vehicle operation, dirt, soot, fuel impurities and other sediments will inevitably accumulate in the exhaust system pipes. Gradually, they will settle on the walls of the muffler and clog its working space.

The driver can notice this only by the behavior of his car:

At first, it will be difficult to gain speed when overtaking.

Then, even with uniform movement, the car will have difficulty maintaining the set speed limit.

Black exhaust from the pipe, loss of engine dynamics.

Cleaning the muffler is a tedious and time-consuming procedure. In addition, if the pipes are clogged, then, most likely, after cleaning, other defects will be revealed - such as rust or burnouts. Therefore, it is more advisable to simply install a new one.

Thermal insulation is completely burnt out

The car owner needs to carefully ensure that the resonator coating is always sealed. The barrel is covered with special thermal insulation materials, which sooner or later burn out during the operation of the machine. If you do not change the insulation in time, you will soon have to change the muffler itself.

To do this, the pipes are dismantled from under the car and separated in parts. A special heat-resistant cloth is glued to the surface, which can be purchased at any auto store. Such protection will ensure a longer service life and significantly reduce the noise of the motor.

What is the VAZ 2115 exhaust system and how to replace the muffler

Causes of breakdowns

1. Location and functionality lead to wear and tear of the gas exhaust system. The main negative factors leading to destruction.
2. The road surface is not ideal. Stones and foreign objects are blown up by the wheels, air flow, holes, and obstacles contribute to mechanical damage and deformation.
3. Driving over rough terrain with a ground clearance of less than twenty centimeters brings hard contact, dents, and scratches.
4. External moisture, falling on very hot surfaces, creates a temperature difference. Thermal changes have a negative impact.
5. Dirt, condensation, and salt compounds corrode the outer coating.
6. Poorly adjusted fuel devices and leaky engine gaskets allow unburned fuel, oils, and coolant to enter the hot exhaust paths.
7. Destructive processes as a result of chemical reactions. Use of reactive additives.
8. The vibration of the power unit affects the welds and damages the suspension cushions.
9. Looseness and wear of connecting components.
10. Violation of manufacturing technologies at the plant.
11. End of guaranteed resource.

Silencer purpose, device, operation

An important element of the exhaust system is the muffler; operating a car without it is impossible. As a rule, the muffler is located at the rear of the vehicle and, in conjunction with the exhaust system, serves to remove harmful gases from the engine, bypassing the vehicle interior.

Car mufflers are made from stainless, aluminized and regular black steel. Stainless steel “silencers” are practically not available for sale due to their high cost and long service life (their service life is 10–15 years). Aluminized mufflers are installed on 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 are rarely used.

What is a “glushak” for?

Main functions of the muffler:

• reduction of noise during fuel processing;
• reduction in the rate of gas release and their temperature.

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.

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

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

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

Which is better?

Over time, the bellows of the VAZ 2114 air filter become clogged or for other reasons become unusable; there is no point in repairing it, and no one does so - it needs to be changed. At this moment, the motorist is faced with the question of which pipe is better to buy to replace the old one (driving without it is not an option, as explained above).

First of all, you need to find out the size of the corrugation that you need; there are situations when, even if you buy an original factory pipe, it does not fit, and therefore you have to cut off a large piece from the part, which is unacceptable.

The price of this corrugation greatly depends on its type and manufacturer.

There are 2 types of corrugations:

1. Interlock is a four-layer pipe (corrugated hose), in which 3 of the layers are external and one is internal. This is a more expensive version of the part, but also of higher quality. The service life of such a spare part will be 5-6 years.
2. Innerbraid - differs from its older sister in that it does not have an inner layer. The declared service life is 4-5 years, while the operation of the air filter and engine itself is not noticeably affected by the absence of the inner layer. Most car enthusiasts choose this option and simply change it every 2-3 years.

Corrugation quality

You should also know that the ideal option is when the corrugation on the VAZ 2114 is installed from Priora, it is suitable in 100% of cases, and in terms of service life it is in no way inferior to foreign analogues.

By the way, there are situations when the corrugation behaves as if it was burnt, but there is no visual damage to the part itself, in this case, most likely, oil got into it, do not rush to buy a new one, because we will figure out how to clean it.

Tuning the exhaust system of VAZ 2114

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

As a rule, the first thing professional “tuners” pay attention to is the intake manifold. By the way, this element is also called a “spider” for its peculiar shape.

An upgraded intake manifold is installed instead of the standard 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.

Removing the catalyst

In addition to installing a more advanced exhaust pipe, fans of fast driving very often resort to complete dismantling of the catalytic converter. The motive for this decision is simple - removing the “obstacle” in order to increase the throughput of the exhaust system. Of course, this significantly increases the exhaust toxicity level. However, the toxicity of the exhaust (without a catalyst) fits well within the framework approved by current legislation. That is, operating 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 the catalyst

At the same time, a small wire “washcloth” is located inside the flame arrester, which eliminates the occurrence of micro-fires.

At the same time, in order to prevent rapid destruction due to corrosion, the body of a homemade 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 who want to modify the exhaust system make it themselves. In principle, there is nothing complicated about this - you just need to know how to use a cutting machine (“grinder”) and a welding machine.

How to replace the muffler on a VAZ 21142115

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:

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.

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.

Roar, shooting, condensation and other reasons to look under the car

It's easy to spot muffler problems. It is difficult not to notice extraneous sounds coming from under the car, or a sharp change in the tone and volume of the response to pressing the gas. It is not uncommon to notice fluid leaking or even splashing from the exhaust pipe. All these are signs of malfunctions, but do they all indicate problems in the exhaust system?

Fluid in the muffler

Fluid dripping from the exhaust pipe is a common occurrence. However, it is worth distinguishing what kind of liquid it is. If it's water, there's nothing wrong with it. When the ambient temperature changes, moisture from the air condenses on the surfaces of the muffler. If a steel muffler is used, this can lead to corrosion, but usually the Priora exhaust system uses aluminized steel or stainless steel, which means that damage from water will be minimal. In cases of heavy accumulation of water, experienced motorists usually drill a drainage hole in the “barrel” of the muffler.

If there is excessive accumulation of water in the muffler, in winter you may encounter icing of the exhaust pipe

If antifreeze drips from the exhaust pipe, the fault should be looked for not in the muffler, but in the engine. The reason may be wear of the cylinder head gasket, as well as depressurization of the block itself. Antifreeze in the exhaust pipe is a symptom of serious problems, and if it is detected, you should immediately diagnose the engine.

Pops and shots from the exhaust pipe

Popping noises coming from the muffler indicate a malfunction. However, this is also a malfunction of the engine, not the exhaust system. Shots or pops from the exhaust pipe indicate that the mixture of air and gasoline does not burn out in the cylinder block, which means that when you hear them, you should check the spark plugs and spark plug wires, as well as the serviceability of the gas distribution mechanism. Problems with combustion of the mixture are not a symptom of a muffler failure, but they can be its cause.

Video: this is what pops from the muffler sound like

Knocking from under the car

A knocking sound from under the bottom of the car while driving or rattling from vibrations is an unpleasant phenomenon. The muffler may touch the gas tank or the underbody. There are several possible reasons for this.

1. First of all, check the rubber muffler hangers. Their wear leads to loosening of the entire exhaust system. These mounts are sold at most auto parts stores. Their price usually does not exceed 100 rubles per piece. Replace the suspension with new ones and the knocking will stop.
2. It is worth checking whether the clamp connecting the main muffler and the additional muffler is loose. If necessary, replace the fastening bolts and nuts. For replacement, it is best to use fasteners made of heat-resistant materials.
3. Using the wrong model of muffler with pipe bends that differ from the original spare part can lead to contact between the exhaust pipe and various components of the car: the body, the gas tank and even the suspension. Be careful when choosing a muffler.

Lowered the car - the muffler is knocking

When installing a short-travel suspension on a Priora, tuning enthusiasts often encounter a situation where the suspension beam, which has moved closer to the body, begins to touch the muffler. This problem can be solved by replacing the muffler hangers with new ones of a more suitable shape.

Loud roar at revs

If a vehicle's exhaust system loses its seal, it cannot effectively reduce the volume of exhaust emissions. In this case, the exhaust often takes on a “pseudo-sports” sound. Therefore, if the muffler growls, you should look for a gap in it. It can be on the muffler body or on the pipes. It makes sense to check the connections and their fastenings. If the metal from which the muffler is made is of low quality, the exhaust pipe may burn out due to temperature. Time, corrosion and the quality of domestic roads cause damage to the exhaust system.

Pressure and temperature can cause holes

A burnt or broken muffler is easiest to replace. If depressurization occurs at the joints, you can limit yourself to replacing the sealing ring and the necessary fasteners.

Supercharger compressor

Mechanical superchargers are one of the best tools for increasing power and torque. They began to be used in the automotive industry 80 years ago. The operating principle of the device is simple: the fuel-air mixture enters the engine cylinder and is compressed by a piston. The spark plug ignites it, causing an explosion. As a result, the piston moves downwards cyclically. The larger the engine volume, the more mixture it enters, and as a result, power and thrust increase.

Algorithm

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. A weak point or “sore” is also
the burnout of the gasket
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%.

Monitoring the performance of the neutralizer

carries out an oxygen sensor that scans the content of lead oxide in the gas environment. Cars equipped with such a device are strictly prohibited from using leaded fuel. Faulty ignition or incorrect adjustment can cause premature failure of the converter. Unburnt gasoline coats the ceramic plates, which makes it difficult for gases to flow out and clogs the system. The first sign may be a sudden loss of engine power. Accordingly, repair or maintenance work is just around the corner. With this discussion of the topic, the exhaust system on the VAZ 2115 is finished. Let's hope that our tips and recommendations will help many drivers gain experience and help them quickly find the source of the breakdown.

Useful tips

Finally, here are some useful tips that will help your car muffler last longer.

1. Inspect the exhaust system at least once a month. This will allow you to timely detect existing problems and eliminate them through minor repairs.
2. Try to avoid sudden cooling of the muffler while the engine is running. This way you will protect it from premature corrosion.
3. Check the attachment of the muffler to the bottom. Excessive vibration will not have a positive effect on its condition.
4. Monitor the performance of the oxygen sensor, because the amount of oxygen in the combustible mixture depends on its information. If its correct concentration is violated, it can burn out in the exhaust manifold or even in the catalyst.
5. If you really had to buy a muffler, choose a model with optimal quality and price.

Exhaust system VAZ 2114 stock and hound

Children are the flowers of life, and they don’t necessarily need to understand the intricacies of exhaust systems, but the kid made the right verdict - if it makes noise, it means it’s a hound, that is, a sports one. It's time for grown-up guys to understand the difference between stock exhaust systems, reconfigured and mutilated, which are only suitable for scaring away non-migratory bird species. Not everyone, however, understands this, or does not understand it quite correctly, so we decided to look into this delicate exhaust issue so that the concepts of “direct flow”, “crab 4-2-1” and other magic spells of tuners acquire a meaningful outline.

To implement this plan, you must first understand the standard exhaust system of the car, because its tasks include not only noise suppression. In fact, the 2114 exhaust system is a complex complex that solves a lot of problems. Noise suppression is only one of them, and not the most important for the engine. The pipe should not choke the engine, but work in balance with the intake system and fully comply with the design features of a particular engine. Precise tuning of the exhaust system is impossible without deep knowledge, laboratory conditions and precision instruments, so talking about tuning it in a garage is pointless. And that's why.

Criteria for choosing corrugations for Priora

Auto repair shop workers advise focusing on three criteria when choosing corrugation:

• Specifications.
• Quality.
• Price.

Characteristics. Selected corrugation, which does not fit in size (length, diameter, shape), money down the drain

Moreover, it is necessary to take into account the dimensions of the old corrugation and pipe. That is, in order for the part to fit exactly, you need to take practical dimensions

To do this, before replacing, you need to remove the old corrugation. And to cut the part and take measurements, it is better to use the help of experienced car enthusiasts, or even better, car service technicians, where the new corrugation will be installed, and its installation will be covered by a guarantee. Quality. It would be unnecessary to say that you should not purchase a used part. No one will provide insurance against the purchase of defective corrugation on the Internet, by hand or at the car market. Ideally, purchase the part from car services that have quality certificates.

Replacing the muffler for VAZ 21142115

Muffler failure on a car can happen for various reasons:

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

Signs of a malfunction most often manifest themselves in increased exhaust sound: the car is very loud, rumbles, an abundance of exhaust gases appears from under the car in the muffler area and the smell of unrefined fuel.

How to change the "glushak" with your own hands

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

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

It is recommended to purchase replacement parts from trusted suppliers, as otherwise you may stumble upon a low-quality fake.

If all of the above corresponds to the parameters, you can begin dismantling 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 additional muffler pipe and the main muffler pipe.

How to remove the muffler

It is recommended to dismantle the unit in the following sequence:

1. Before unscrewing the nuts, treat the threads with WD-40 or rust remover and wait 10 minutes.
2. Using a socket wrench or a 13mm socket, unscrew the two nuts holding the clamp.
3. After removing the clamp, remove the sealing ring.
4. Remove the rubber pads holding the muffler.
5. Disconnect the muffler from the resonator.

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.
