Inexpensive repair and replacement of Lada Priora muffler corrugations

Muffler corrugation Lada Priora

Which muffler corrugation should I buy for Lada Priora? First, you need to know the size of the muffler corrugation. You can buy a muffler corrugation according to factory sizes, but when replacing the muffler corrugation, it turns out that you need to cut off a larger piece of the muffler pipe and the standard size will be insufficient. They buy a muffler corrugation when it has already burned out. The muffler corrugation is not repaired or welded.

The price of a Lada Priora muffler corrugation depends on the type of corrugation. There are two types of muffler corrugations: Interlock and Innerbraid. The most expensive and high-quality corrugation is Interlock: the corrugation consists of four layers, three outer layers and one inner layer. The second option is Innerbraid: three layers, both external. Frankly speaking, there is a difference between the corrugations, but it is not colossal.

In most cases, they buy a three-layer corrugation version. You may also need muffler rings and additional gaskets.

Silencers of domestic VAZ

For different models of front-wheel drive VAZs (VAZ2170, 2172), they may differ depending on the type of body, the method of fastening (pin-type, hook-shaped), as well as the manufacturing principle - welded and newer rolled ones. True, the original manufacturer produces only stamped-welded mufflers. They can be longer or shorter, depending on the length of the body. In particular, longer ones are installed on the VAZ Priora 2170 sedan and station wagon than on the hatchback. In addition, there may be differences in the bending of the pipe itself.

During operation, the muffler is exposed to high temperatures, corrosive gases and moisture. The combination of these negative factors leads to cracks and damage to the seams. Auto repairmen often patch the muffler, but replacing it is still inevitable. In order for the muffler to last for a long time, first of all you need to choose products from a manufacturer that provides a quality guarantee. Muffler for VAZ 2170, (Kalina, Priora) for different body styles produced by AvtoVAZ, UTAS LLC, Ekris LLC, Polmostrow can be purchased in our online store at an affordable price. When choosing, you also need to take into account the quality of the material and the method of execution of the case.

When the corrugation fails

Automotive technicians fully agree with the recommendation of corrugation manufacturers that this part must be replaced if three of its qualities are violated:

1. Flexibility. When the corrugation does not meet the criteria of plasticity, that is, it does not behave like a spring, bending and unbending, its presence is simply meaningless. Vibration will be transmitted to the muffler and suspensions from the internal combustion engine, which will lead to their wear and loosening of the fastenings.
2. Tightness. If gases escape through gaps in damaged or burnt braid, it will result in loud noises and a burning smell. Corrugation in this case also becomes a headache for any Priora driver.
3. Strength. Worn corrugation will not last long. If there are symptoms of its rapid failure, replacement will help.

Basic faults

There are many muffler malfunctions, but the most common are two:

1. Problem with lambda probe. The lambda probe is a sensor that monitors the emission of waste substances to ensure ideal operation of the exhaust system. The sensor fails after a hundred thousand mileage. Unfortunately, the sensor is not repaired, but replaced with a new one.
2. If you hear a characteristic knocking sound in the muffler, this may also indicate that a crack has formed in the muffler itself. This symptom is confirmed by the noise increasing as the engine speed increases and decreasing when the engine is turned off. The malfunction can be eliminated in two ways: by welding or completely replacing the part, and the second option, of course, is more reliable.

Factors that indicate that the Priora muffler corrugation needs to be replaced

Auto repair shop workers advise paying attention to the following signs that indicate breakdowns and that replacing the Priora corrugation is inevitable:

1. The engine began to run louder than usual.
2. The smell of exhaust gases can be felt, which can penetrate into the car interior through the ventilation.
3. Motor power decreases.
4. A rattling sound is heard under the bottom of the Priora.

These are the main symptoms that can begin to appear all at once or one after another, but in a fairly short time.

Initially, you can carry out a visual inspection yourself - breaks, burns and damage to the corrugation braid are usually visible to the naked eye. But even if such traces are not visible, this does not mean that the part has exhausted its service life.

The best resonator manufacturers

Each resonator has a set of pros and cons that manifest themselves during operation. They are noted by car owners and service station technicians. When choosing, you need to pay attention to the features of each model.

Description. The CBD brand belongs to a domestic company that specializes in automotive parts, in particular for the exhaust system.

The range of resonators is divided into two categories. There are standard models that are made specifically for a specific car brand, as well as universal ones that can be connected to most exhaust system pipes.

During production, all quality requirements are met, including GOST, as well as international standards.

The manufacturing process uses carbon or aluminized steel, which are resistant to wear and rust.

This, combined with modern manufacturing technologies, has led to an increase in the service life of spare parts.

Equipment. May vary depending on series. Some resonators are supplied complete with a muffler and other elements. The standard kit includes the spare part itself, fasteners, as well as adapters, a gasket, and a can. There are resonators sold separately.

Life time. The warranty period varies from 12 months to 2 years depending on the line.

1. Thickened body and long service life.
2. High-quality performance without defects.
3. Large assortment with universal models available.
4. Acceptable prices.

1. There are fakes made from low-quality metal.

Atiho

Description. The Atiho brand specializes in exhaust systems. For most brands of cars, you can select mufflers, resonators, catalysts and any other spare parts. The company produces spare parts using European technologies.

The resonators are free of defects and have low prices.

Take into account that the quality meets international standards.

Equipment. It can be full-fledged, that is, with other elements of the exhaust system, or single with clamps and a can. On the market you can find special sets of resonators with muffler for sports cars.

Life time. Guaranteed service life is 1 year. In practice, spare parts are used for 2-3 years if they are treated with care and the correct model of spare parts is selected.

1. Inexpensive quality spare parts.
2. Large selection for different cars.
3. Good level of sound insulation.
4. Similar to the originals.

1. There are counterfeits, which are characterized by poor performance of spare parts and defects.

Stinger

Description. The American brand is one of the aftermarket leaders in exhaust system spare parts. Resonators and mufflers are supplied all over the world and have certificates confirming compliance with international and European standards.

There are several lines of resonators. You can find stainless steel and regular models in the market. American products are distinguished by dimensional accuracy, which allows you to replace original parts without adjustment.

Equipment. May include the resonator itself, a jar, a spider, and gaskets. There are extended configurations that consist of several spare parts for the exhaust system. You can also find single spare parts, but in this case the risk of buying a fake increases.

What leads to damage to the Priora corrugation

Any auto repairman conventionally divides the reasons for failure of parts into external and internal. Corrugation is no exception in this regard.

Within one system, all parts, one way or another, influence each other.

1. Catalyst malfunctions. This is the most common cause of corrugation failure. So when replacing it, you need to check this device too.

1. Wear of fasteners and hangers. A loose system increases the load on the corrugation from engine vibration, which leads to its failure.
2. Problems with other systems. This could be the transmission, engine mounts, etc. – anything that increases vibration.

• External reasons:

1. Corrosion. The corrugation is located in that section of the exhaust system where it is significantly affected by external aggressive factors. This is road dirt, moisture from puddles, reagents that are generously flavored with the surface of Russian roads in winter. The material of the Priora corrugation is stainless steel, and welded seams are more susceptible to corrosion.
2. Strikes. On an uneven road, a car, overcoming potholes, can hit the bottom of the road. Potholes, hummocks, and stones can either cause pinpoint damage or simply rip the braid of the part.
3. Incorrect installation. Welding requires care and precision. Uneven seams on joints will come apart faster. In addition, the braid could be damaged during unscrupulous repairs of other components near the corrugation.
4. Wear and tear from old age. This reason has little to do with the motorist. The part will not last forever, especially if you take into account the fact that it constantly experiences increased loads.

How to determine whether a muffler is faulty

Self-replacement of the Lada Kalina thermostat step-by-step instructions

In fact, this is the element that is most often exposed to high temperatures. Over time, this element fails due to corrosion, burnouts, impacts on uneven roads, or constant accumulation of condensate in the pipe.

Corrosion causes the muffler body to lose its seal.

If the muffler is faulty, the driver will immediately notice this:

• the “glushak” will start knocking on the body;
• the car will lose its dynamism;
• you can hear pops and a strong roar in the exhaust pipe;
• Antifreeze is leaking from it.

Why does the silencer fire?

Most often, car owners complain about loud popping noises in the exhaust system while driving. The muffler can only fire for one reason: the air-fuel mixture does not have time to completely burn out in the engine, so ignition occurs in the exhaust pipes.

This can seriously damage the integrity of the pipes. Therefore, at the first claps, you need to check the following car systems:

• spark plug wires (if, after replacing the spark plugs, the wires were connected incorrectly, problems with engine operation may occur);
• gas distribution control;
• timing belt performance.

That is, the occurrence of pops is not related to the performance of the muffler itself, but directly affects the service life of the pipes.

Knocks from under the body

The muffler may knock:

• about the bottom of the car;
• about the fuel tank body.

In any case, the impact of the pipe on the surface quickly deforms the coating, as a result of which the part loses its tightness. There are two reasons why it lost its original position under the body and began to hit other surfaces while driving:

1. The rubber suspensions are worn out. You just need to buy new rubber bands and replace them. The muffler will return to its normal position and the knocking will stop.
2. After replacing any elements of the exhaust system. It is quite possible that certain parts were connected incorrectly, the nuts were not tightened correctly, the reinforced gasket was inserted on the wrong side, etc. To understand this problem, you will need to carefully check all connections and elements. Often knocking noises occur due to improper installation of the short stroke.

Antifreeze in the muffler

Antifreeze that drips from the exhaust pipe may indicate one serious problem with the engine - wear of the cylinder head gasket. Therefore, coolant gets inside rather than being used in the cooling system.

It is recommended to immediately take measures to diagnose the engine unit.

Condensation accumulates in pipes

Drivers often notice a phenomenon such as water in the exhaust pipe. Sometimes condensation appears even in winter. Of course, for steel pipes of the exhaust system, moisture is considered the main enemy - here it’s not far from corrosion.

However, the formation of condensate in pipes is an irreversible process. This cannot be called a malfunction or defect of the exhaust system, since due to high temperatures inside the pipes and lower temperatures outside, the exhaust gas turns into a liquid state. This is why condensation forms. Some drivers drill small holes in the muffler to make water leave the muffler faster. This really helps to avoid the rapid development of corrosion.

This phenomenon can often be observed on all cars.

Criteria for choosing corrugations for Priora

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

• Specifications.
• Quality.
• Price.

Characteristics.
The selected corrugation, which does not fit in size (length, diameter, shape), is a waste of money. 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.

Price. You have to make a choice of corrugation by type - with double or triple outer braid. In terms of price, they do not differ so significantly (the price of corrugations is generally not as high as it might seem), only the first type of corrugation is more rigid, it should definitely be installed on used cars. The cost also depends on the manufacturer. You can purchase imported ones - Italian Hydra or German Ehler corrugation. Their quality leaves no doubt. But the price is, of course, higher. And it is possible that you will have to wait for delivery if it is out of stock. Among the parts from domestic manufacturers, it is quite possible to select high-quality and inexpensive corrugations.

VAZ 2114 air filter corrugation: rules for selection and replacement

First, let's figure out what the VAZ 2114 corrugation in the air filter is and why it is needed at all. The part is a pipe that is attached to the air filter and is responsible for drawing air into it.

Many motorists drive without it, but this is wrong. In working condition, the corrugation should take in air that passes through the gap between the hood and the radiator; if it is not there, then the air that has already passed through the radiator and cooled it is sucked in.

The temperature of such air is much higher, and as a result, the machine heats up, and its power drops, and if you also turn on the fan, then all the heat will go straight to the filter. If you drive little or it’s winter outside, then the drop in the car’s power will be less noticeable, otherwise even a novice motorist will feel the drop in engine power.

Where to go if you need to replace the corrugation on a Priora

The car enthusiast has three options for replacing the Priora corrugation:

1. Independent replacement of corrugation on Priora. Without the conditions for repair (inspection pit or lift), a set of tools, an electric cutter and a welding machine, the corrugation cannot be replaced. Plus, you need to choose exactly the right part and purchase it. Without all this, and also if you have the slightest doubt in your abilities, it is worth considering other options.
2. Replacing corrugations with self-taught people. Typically, handicraftsmen have a garage with tools and equipment at their disposal. Perhaps they also have some experience in replacing corrugations (which is not always noted). Having taken money for work, they will not give guarantees either for the part or for their work. Rattling noises, engine noises and fumes may appear soon after contacting such “Kulibins”.
3. Replacement of corrugations by professionals. The quality of the part, low prices and competent replacement are guaranteed if you contact our car service:

• you save time, nerves and money by trusting specialists;
• At your request, the entire exhaust system can be diagnosed and, if necessary, other elements can be repaired;
• you will receive guarantees for all work performed.

The main malfunctions of the Priora exhaust tract

Do-it-yourself direct-flow muffler, is it worth installing it on your car?

Due to the fact that the operation of these components is associated with high temperatures, the most common breakdown is the burning out of some part. This could be the gasket under the manifold, or the wall of the muffler, catalyst or resonator. A separate part is the malfunction of the particulate filter or afterburner. But they are included in the section for repairing the injection part of the car, just like the Priora oxygen sensors. In other cases, it is either mechanical damage or simple rust.

The appearance of extra holes in the system is determined immediately and for sure. The engine exhaust just becomes loud and unpleasant. There is a crackling sound and sounds vaguely reminiscent of shooting. In this case, you need to go to the inspection hole, find the hole and replace the damaged unit. Relevant video on this topic:

I have a choice between Tolyatti and Universal (Baltics or something).

they say that it is quieter than the Togliatti one. Is it stainless steel? I think it might be better to weld a metal compensator into it? Or how to screw the old one in?

Please explain what a “metal compensator” is? and what benefits does it provide? Thank you.

I think it might be better to weld a metal compensator into it? Or how to screw the old one in?

I'm thinking about which side to put it on. IMHO, you need to take it as long as possible, it makes no sense to set it less than 100, since the corrugation is hard.

how to hold out until the weekend and not get stuck.

Then we will select the diameter of the corrugation empirically, whatever is offered on the market!

Main components of the Priora exhaust system

As already mentioned, this is not one element, but several:

1. Timing (gas distribution system) exhaust valves.
2. Exhaust manifold with particulate filter (catalyst).
3. Oxygen sensor (Lambda probe) 2 pieces.
4. Middle part with resonator.
5. Tail section with muffler.

Each of these parts must be considered separately.

Release of gases in the cylinder head

This is part of the operation of the gas distribution mechanism. A full description of this mechanism is a separate issue of engine operation. It is enough to mention here that the 8 exhaust valves open in exhaust mode and the piston pushes the exhaust gases into the system. Namely, into the exhaust manifold.

Catalyst or particulate filter in the exhaust manifold

This is one of the most complex and expensive components of the entire exhaust gas system. Essentially, this is a device for afterburning unburned gasoline particles using catalysis. For this purpose, the thin walls of the longitudinal filter honeycombs are made of a special material. Contacting them, gasoline burns (figuratively). The output is ordinary water.

Set of Lambda probes for Euro-3 system

What is Euro 3 standard? In fact, this is the level of purification of car exhaust gases. It is according to the levels of vehicle access to Europe that these systems are distributed. There are several levels:

• Euro level.
• Euro 2 threshold.
• Euro-3 (basic for Priora).
• Euro-4 (Subsequent models and the latest “Priors”).
• Euro-5.

In the first option, a particulate filter was added to the exhaust system. It is mentioned above. But in system No. 2, electronics control has already been connected. A special, rather complex and expensive sensor was developed. Lambda probe or oxygen sensor. Thanks to a special coating, its resistance changes its value depending on the saturation of the exhaust gases with carbon monoxide. That is, carbon monoxide.

To more accurately understand the meaning of the Lambda probe, it is worth briefly describing the history of Euro standards. So.

To reduce toxicity, an afterburner was installed in the exhaust system (the particulate filter described above). This was the Euro system. Further, with the development of the electronic component of the control system, the idea of ​​exhaust quality control came. And installed 1 oxygen sensor. It was placed in the system directly into the collector. Before the afterburner. This allowed us to make adjustments to the gas saturation table in the program. The system with one sensor was called Euro-2.

However, savvy motorists quickly realized that the particulate filter, which reduces engine power, can simply be thrown out. Which is what they began to do with success. Then, after the afterburner, another Lambda probe was inserted into the system. And he already informed the computer that the filter was not working. And accordingly, he again cut back on fuel. This became the new Euro 3 standard. Well, Euro 4 and 5 are just a modification of the software and replacement of fuel to the European level, respectively. The latter, if nothing interferes, should be carried out in Russia by the end of 2022.

This is what the oxygen sensors in the Priora exhaust system are for.

What is the purpose of the resonator in the Priora exhaust device?

It is also called an auxiliary muffler. It is an exhaust system pipe bent at an angle and having an extended section in one place. This makes it possible to initially smooth out the sound vibrations escaping from the engine when releasing gases.

The auxiliary muffler is located immediately behind the manifold and catalyst. And immediately behind it comes the muffler itself.

On some Priora models, two parts, the resonator and the main muffler, are made as a single unit. But the collapsible design is more convenient both in operation and in repair.
