As you know, many expensive cars are equipped with powerful power units. To properly ensure the removal of combustion products, manufacturers usually also install a double exhaust pipe on them.
Moreover, it is not uncommon when a serial (insufficiently powerful) engine is replaced with a stronger unit, and a dual system is also installed on domestic cars. Sometimes this option is also installed during tuning, and here it is purely decorative.
In this article we will tell you how to install a double exhaust on your own Priora. It is worth noting that such an improvement can be easily mounted on any type of the above-mentioned model, including:
- hatchback;
- sedan.
Advantages of dual exhaust
You may ask, what is the point of tuning the exhaust system if it already functions flawlessly? The bifurcated muffler has special advantages:
- Increasing the intensity of exhaust gas removal by reducing resistance, and as a result - increasing engine power;
- Additional reduction of noise level during operation of the exhaust system;
- Giving the car an aggressive, spectacular “sporty” appearance;
- Providing a smooth, unique “noble” sound to a running car.
There are two options for installing a dual exhaust on a Lada Priora - purchasing a bifurcated muffler in a specialized store and making your own system from individual elements. The first tuning method is quite expensive, but the second requires only certain skills, some parts and the simplest tool.

There is no need for her to be a priori, a collective farm
do not bother! You don't need this attachment. there's no use for her here.
Look at my photos. I have a large nozzle there, now I installed a small one. Both are curved and everything is fine. Namely, I haven’t met anyone from 15)))
There are 3 bolts on it. You put it on and screw it on.
In general, we sell attachments for our muffler)
on the 15 it is curved differently, if you take it on our plug, will everything look straight from under the bumper?
Well, I don’t know about the 15 shki, of course, but in a store I once bought an attachment and told the seller “I need a VAZ 2115” and that’s it. And as for the attachment for our silencer, I don’t know that they sold curved ones and that’s it.
why do you need a 15 if you have a Priora?) or are the ones from 15 better suited? Another question, do you need to do something with the jammer itself? bend cut? Or did you just hook the nozzle and that’s it?
Well, when I went into the store and said “give me an attachment for the Priora,” they widened their eyes at me. It’s just that we don’t have many auto parts stores, and having looked all over, I couldn’t find one for the Priora. Then I stopped by one store and saw the attachment I needed, curved (on it had a sticker 2115) so I took it) I didn’t do anything to the muffler, I just screwed it on and that’s it) well, I wouldn’t recommend you install it - for me, over the course of several months, the end of the muffler rotted. And although my friend’s was fine)
Split design options
Note that there are several design solutions for installing a homemade dual exhaust on the Lada Priora. Let's look at the most common options:
- Divergence of two outlets from the main muffler pipe (at the rear beam);
- Wiring of two mufflers directly from the resonator;
- Installation of two resonators with mufflers immediately after the catalyst;
- The output of two pipes from each of the dual mufflers.
So, there are many ways to tune the exhaust system, the final choice depends on which option suits you best.
Which muffler to choose
Before changing the muffler, you need to select it. There are a lot of options on the market, and seemingly identical mufflers can differ in price by two to three times. We recommend that you pay attention to the thickness and type of steel, as well as the country of manufacture.
Stainless steel or aluminized steel
Mufflers for cars of the Priora family are made of steel of various thicknesses. The thicker the steel, the stronger the muffler. The type of steel is no less important. Most car enthusiasts prefer stainless steel that has been proven over the years. However, modern aluminized steel is not inferior to it in terms of resistance to corrosion, and is significantly superior in overall strength and ability to absorb vibrations. This means that an aluminized steel muffler will be quieter than a similar one made from stainless steel.
Manufacturers and prices
Exhaust system parts for Lada-Priora cars are produced not only in Russia. There are mufflers and resonators made in Poland, Turkey and Germany.
Polish and Turkish mufflers are usually cheaper than German ones. However, their service life is half that of the best domestic models and mufflers from Germany.
A muffler for a Priora costs from one to five thousand rubles. At the lower end of the price range are models made of thin steel; aluminized models usually cost at least three thousand rubles. The situation is similar with resonators. Prices for them start at about one and a half thousand rubles.
Workflow Stages
Types of Dual Homemade Silencers
Let's consider the simplest and low-budget method of installing a dual exhaust on a Lada Priora with the installation of outlets from the muffler pipe under the rear beam of the car. Note that here you can choose one of two options:
- Distribution of pipes of different lengths with welding of branches to the main muffler.
This is interesting: Video recording and countermeasures
Two pipes of different lengths are welded to the main muffler pipe
- Welding two pipes with similar lengths, angles and number of turns to the main muffler pipe.
Two identical pipes are welded to the muffler pipe.
Remember that different lengths of pipes, although they affect the amount of gases released (this will be especially noticeable at high engine speeds), do not affect the operation of the engine itself.
Preparing for work: tools and materials
To carry out a full cycle of work, we will need to prepare a set of simple tools and a number of inexpensive materials:
- wrench (socket, open-end, socket) to “13”;
- electric drill with 1.5 mm drill;
- Phillips screwdriver;
- self-tapping screw 4 mm - 2 pcs.;
- standard exhaust system fasteners (clamp + ring);
- muffler cushion - 2 pcs.;
- fastening bracket (holder - bracket).
Clamp with O-ring, homemade bracket, muffler cushion
At the preparatory stage of work, you need to take the necessary measurements and draw up a simple diagram of the design of the double exhaust. There is simply no universal drawing that would be suitable for each individual project. Professional craftsmen advise taking all measurements at the place of work, transferring the data onto paper in a form convenient for you.

Note that the exhaust system of the Lada Priora sedan and station wagon differs from the same equipment installed on hatchback cars in the length of the main muffler pipe. Installing a dual exhaust on a car with such a body for the first two modifications will result in the system pipes protruding from under the bumper by 150–160 mm.
How to make it yourself
Let's look at the process of installing a bifurcated muffler using the example of a finished sample - all the steps we performed are suitable for installing any structure of this type. The only nuance that can affect the progress of work will be the possible deviation of the pipes of the independently manufactured system from the fastening elements of the original muffler. However, this is not a problem, since all brackets can be easily made and installed with your own hands.
We install the car on a lift or inspection hole, prepare all the necessary tools, be patient and get to work:
- We dismantle the original main muffler by disconnecting the clamp at the point of its attachment to the resonator (additional muffler).
- We will hang the right part of the new structure on its seat, installing it on the existing cushions (replacing them in case of critical wear). We do not attach the left side of the muffler yet, but only connect the common terminal of the dual exhaust to the resonator, slightly “baiting” the clamp and the O-ring.
Installation of a part of the structure on the seat of the original muffler - Let's attach the left bend to the side member on the bottom of the car, mark the attachment point of the bracket-bracket.
Left part of the structure, mounting bracket and muffler cushion - Using a drill, drill two holes and securely fasten the bracket with self-tapping screws.
Preparing holes for installing the bracket-holder - We hang the muffler outlet on the bracket using a fastening rod, after inserting the cushion into the holder bracket.
Installing an additional muffler outlet - In our case, the elements of the dual exhaust need to be connected to each other using a clamp with O-rings (do not tighten too much). We exclude this stage of work when installing a solid structure.
Connecting the branches to each other using a clamp - It remains to check the angle of the dual exhaust outlets relative to the ground. After making sure that they are at the same level, tightly tighten the clamps at the junction of the inlet pipe with the resonator and at the junction of the two pipes (if such an element is in the design).

Exhaust system design
The exhaust system is designed to safely remove exhaust gases, as well as reduce noise levels and harmful toxic substances. The latter has become relevant due to the increase in the number of cars. Lada Priora is equipped with just such a system.
How to make a split exhaust pipe
The exhaust system of a Lada Priora car consists of the following main parts:
- Main muffler;
- Auxiliary muffler;
- Exhaust manifold with converter.
All these components are interconnected in such a way as to ensure tightness.
Main muffler
It is a metal structure with an ellipse shape in cross section. Inside it there are several partitions connected to each other in a certain way to dampen the sound wave. A pipe approaches it from both ends. The attachment to the body of the Priora car is made using two soft damping pads that isolate it from vibration.
Auxiliary muffler
Exhaust system of Lada Priora It is located after the exhaust manifold of Lada Priora. The attachment to the bottom is also made using two pillows. The exhaust system of the Lada Priora is designed in such a way that the main and additional mufflers are hingedly connected to each other. This reduces the mechanical load on the pipes when hitting obstacles, and also reduces the impact on the body.
Exhaust manifold with converter
Its task is to neutralize harmful substances and collect gases from each cylinder. The exhaust system of the Lada Priora has a neutralizer built into the manifold. This makes the design compact. The connection to the exhaust pipe of the additional muffler is made using flanges, between which there is a sealing gasket. In addition, a locking plate prevents the nuts from unscrewing due to vibration.
The exhaust system of the Lada Priora provides for the placement of oxygen sensors inside the manifold, as well as thermal protection of the bottom and steering using screens.
This prevents fire and melting of the sound insulation. The exhaust system of Lada Priora has the highest temperature closer to the engine. That's why the screens are located there.
Examples of finished structures on the Lada Priora car

Bottom view Spectacular view of the Lada Priora with dual exhaust So, we have established that tuning the exhaust system of the Lada Priora is not such a troublesome task. The main thing is to remember that the exhaust pipes of the car are located in close proximity to the fuel system. Elements of a homemade double exhaust must be wrapped with asbestos cord, which will provide thermal insulation of the parts and prevent fire.
Hello! My name is Alexey, I am 45 years old. I am interested in studying all types of technology and independently servicing personal vehicles, and I read a lot. I consider my favorite hobbies to be the most effective escape from stress: photography, numismatics and home renovation. (2 votes, average: 4.5 out of 5)
Execution of work
The manufacturing process of the structure itself is shown in the video, which is located at the end of the article, so we will not dwell on it in detail.
We'll tell you more about installation. The machine is installed on a ramp or pit. The further procedure will be as follows:
- completely remove the factory muffler along with the clamp securing it to the resonator;
- the finished exhaust system (its right part) is suspended on original cushions;
- leave the left one unfixed;
- the common output is connected to the resonator with a clamp;
- the left exit is applied directly to the spar and the location of the fastening is marked;
- drill holes there for the bracket and mount it;
- the outlet is fixed.
Before fully tightening all the screws, you need to make sure that the dual exhaust system is located at the correct angle to the ground.
Finally, it is worth recalling that since the new pipe runs in close proximity to the fuel supply system, it must be wrapped with a cord made of asbestos - this eliminates the risk of fire.
This video explains how to make a double pipe:
Forked exhaust on Priora
First of all, the dual exhaust on a car is a sign of its power. As a rule, many foreign automobile industries are endowed with this attribute, the power and torque of engines are quite large and require a more complex system for intensive removal of exhaust gases from the cylinders.
But, there is also such a thing as exhaust system tuning, which is when, for some reason, the serial design of the device is subjected to alteration. The reason for such changes today may even be the desire to simply improve the appearance of the car, make it cool and add imaginary power.
Dual exhaust can be installed on any car, even from a domestic manufacturer. With a competent and careful approach, this will not harm the proper operation of the machine. There are no problems to create a double exhaust on a Priora, this is what will be discussed in this article.
Twin Pipe Types
The following options are currently most popular among domestic car enthusiasts:
- bifurcated outlet installed after the muffler;
- parallel installation of two pipes with mufflers behind the resonator;
- system with 2 resonators and the same number of mufflers.
Moreover, in the latter case, a twin pipe can also extend from each of them. As you can see, each option has its own advantages and disadvantages, so the choice remains with the car owner.
Malfunctions
The Priora exhaust system suffers mostly from corrosion processes that occur due to condensation: vapors settle on the hot surface, which, as the metal cools, turn into destructive drops. Overheating also causes system destruction. The main faults include the following:
- reduced noise reduction;
- breakdown of sensors;
- broken fastenings;
- mechanical defects of parts.
A decrease in the ability to suppress noise occurs due to damage to the partitions. This malfunction is usually indicated by rattling sounds when the engine is turned on. Whatever the malfunction, it requires an urgent procedure for replacing the muffler, because if you postpone this action until later, the problem can worsen and lead to very unpleasant consequences, because the muffler not only reduces the noise level, its second job is to protect against penetration toxic fumes into the cabin, which can lead to poisoning of the driver and passengers. In addition, the muffler affects the operation of the engine, maintaining its power. That is why it is important to approach the issue of replacing the muffler with the utmost care.
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.
- 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.
- 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.
- 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
Tips for choosing
The first thing you should pay attention to when choosing a muffler is the material. The best option is aluminized steel; it is stronger than stainless steel or zinc-alumina steel and is resistant to rust. This part will last about six years. The second is the device of the node. Silencers are divided into several types
- by design;
- degree of noise reduction;
- dimensions;
- presence/absence of an additional body layer.
Third, you should pay attention to the manufacturer and the country of manufacture. As a rule, Polish and Turkish companies cannot please you with their quality, while the Germans, Japanese, and even our domestic parts are quite suitable for the job. And lastly, it’s worth remembering that each model is equipped with a certain type of muffler and you need to know this when buying a part. The price for a standard muffler for the Lada Priora is approximately 3,400 rubles.
What does the price depend on?
To manufacture the body and tubes of high-quality components, special stainless and heat-resistant steels are used, designed to operate under constant thermal load with sudden temperature changes. These mufflers last longer, but they are the most expensive. Spare parts made of aluminized steel or aluminum-zinc will also last a long time. To reduce the cost, “ferrous” alloys are sometimes used.
The larger the muffler volume, the better. Other factors that increase the service life and increase the cost of the unit are thicker walls and complex internal design, as well as additional thermal protection.
