Types and features of flame arresters
In modern automotive technology, manufacturers pay special attention to the exhaust system. One of its important elements is the catalyst. The operation of this device ensures reliable operation of the engine.
However, this element produces significant noise, which increases the requirements for the muffler.
Therefore, very often, car enthusiasts prefer to replace the catalyst with a flame arrester, the price of which is an order of magnitude lower than the total cost of other system components.
At its core, a flame arrester is a type of resonator. Its main function is to stop the rapid flow of gases from the collector, partially cool them and then send them in one common flow. In addition, installing a flame arrester instead of a catalyst is used to minimize the noise emitted during engine operation.
The main requirement for such equipment is a two-layer casing. Moreover, the optimal choice would be to replace the catalyst with a flame arrester made of durable steel with an anti-corrosion coating.
In addition, depending on the car model, it is necessary to select the volume of the new device.
Therefore, it is recommended that only experienced and professionally trained specialists install a flame arrester instead of a catalyst.
Unfortunately, even in Moscow, some workshops use low-quality, cheap equipment. Therefore, very often, instead of installing a catalyst, they install single-layer resonators that do not perform the functions of a flame arrester, the price of which is an order of magnitude higher. Such devices quickly fail, forcing customers to seek help again.
Our specialists install only high-quality flame arresters instead of catalysts.
When replacing the catalyst, they use either universal models from manufacturers such as Walker, Bosal, Ernst or Tesch, or original devices from car manufacturers (provided that they are produced).
Of course, the prices of such flame arresters are much higher. However, if you decide to replace the catalyst with a high-quality flame arrester, you will still benefit, since under normal use it can last for several years.

Catalyst repair and replacement
Our company specializes in diagnostics, maintenance and repair of exhaust systems for foreign cars of Korean, Japanese, European and American production. Main services:
- exhaust system diagnostics,
- removal of errors P0420 – P0430 due to DC tricks or firmware (chipping) of the car’s ECU,
- catalyst repair,
- installation of a flame arrester,
- replacing the muffler corrugation,
- installation of decoys on the lambda probe;
- software disabling rear DC (firmware for Euro-2).
Catalyst repair is our priority service. As spare parts, we use products from European, American and Russian brands - Ferroz (Poland), Eberspacher (Germany), Bosal (Belgium), Walker (USA), AWG (Poland), Mg-Race (Russia) and many others.
Almost any catalyst must be replaced when the car travels a certain distance. Typically this interval is from 100 to 200 thousand kilometers.
However, every experienced car owner can give a lot of examples when the ceramic base of the catalyst was destroyed or burned out after a mileage of 20 - 40 thousand kilometers. The main reason for this situation was low-quality gasoline.
You can find out more about what a catalyst is and how it works on this page of our website.
Many car owners are looking for information about the possibility of repairing a catalyst. Actually there are the following three options:
- replacement with the original neutralizer,
- replacement with a universal catalytic unit,
- installation of a flame arrester.
The first option is obvious, and is carried out by official dealers. Its main disadvantage is the price.
A new spare part for cars such as Mercedes, Audi, Volkswagen, Honda, Mazda and other popular foreign cars costs an average of 1000 - 1500 US dollars.
Considering that most modern cars with engines larger than 1.6 liters have two, three or even four catalysts, it is not difficult to understand the final cost of such repairs.
Replacing the catalyst with a flame arrester
Flame arrestor in section
Any catalyst can be cut out of its body, the car can be flashed for Euro-2, or a fake can be placed on the second lambda probe. The car can be driven, but its sound will change.
Another negative factor of such an operation is the increase in thermal load on the entire exhaust system. To avoid such negative consequences, a flame arrester is installed instead of a catalyst, which is a pipe with chambers to reduce the speed and temperature of gases.
To more effectively reduce noise, some manufacturers, for example Mg-Race, use additional padding. The undeniable advantage of the flame arrester is the reliability of its design, which should last more than 10 years.
You will also be pleased with the cost of the work - on average, installing one flame arrester together with a lambda probe is 8 - 10 thousand rubles.
The flame arrester cannot, unlike the catalyst, remove excess CO, CH and NOx from the exhaust gases. In Russia, there are fairly liberal standards for the content of harmful impurities in exhaust gases, and the use of cars with flame arresters is permitted by law.
A fairly significant share of the Russian vehicle fleet has never been equipped with catalysts. Such cars include almost all GAZ, VAZ and UAZ products produced in the early 2000s. Therefore, we cannot expect any tightening of CO and CH standards in the near future.
However, if the car is driven abroad, the presence of a catalyst may be mandatory.
In the flame arresters section you can learn more about the operation and design of these vehicle components.
Replacing the catalyst with a universal analogue
Universal repair block
Currently, almost all manufacturers of exhaust systems produce universal models of catalysts that can replace original parts. They are made somewhat simpler than the original products. The working fluid of many of them is a steel strip rolled into a spiral, which is cheaper than traditionally used ceramic sieves.
Sometimes the manufacturer saves on sputtering with precious metals (Pd, Rh, Pt, Ru). In this case, the exhaust concentration of harmful impurities will exceed the EURO standard corresponding to the car and the “Check” light will light up. This should be taken into account when choosing a universal catalyst.
We recommend using only certified products from leading brands - Eberspacher, Bosal, Ferroz, Walker and some others that meet the Euro-4 environmental standard. The service life is practically no different from standard parts and on average is about 100 - 120 thousand kilometers.

Exhaust gas catalyst design, how to replace the catalyst with a flame arrester. How to replace a catalyst with a flame arrester?
To solve problems with environmental pollution, each country issues certain laws that limit the permissible level of pollution created by each car. To meet these requirements, automobile manufacturers have significantly modernized the design of automobile engines and fuel systems.
One of the significant changes happened in 1975 - a new device appeared called a catalytic converter (catalytic converter, converter) or simply a catalyst.
Its work is based on converting toxic exhaust gases into harmless ones through the reduction of nitrogen oxides, as well as the afterburning of unburnt hydrocarbons and carbon monoxide. More on this later in the article.
Catalyst, device, how it works
We know from our school chemistry course that a catalyst is a substance that causes an acceleration of a chemical reaction, but the catalyst itself does not participate in this reaction.
That is, the catalyst is directly involved in the reaction and affects the duration of its course, but is neither a product of the reaction that it catalyzes nor a reagent.
Enzymes in the human body are also natural catalysts that are responsible for a lot of necessary biochemical reactions.
In general, a catalytic converter in its operation consists of two different types of catalysts - an oxidation catalyst and a conversion catalyst.
Both options consist of a ceramic structure that is coated with a metal catalyst, usually palladium, platinum and/or rhodium.
The idea is based on forming a structure that provides the largest surface area of the converter in the exhaust gas flow and minimizing the required amount of catalyst, since the cost of materials for it is considerable.
Some modern converters have even begun to use gold mixed with standard catalysts. Gold, by the way, is even cheaper compared to the other listed materials, but it can increase oxidation.
Most modern foreign cars are equipped with three-component catalysts. This indicates that they provide an opportunity to reduce emissions of the three most harmful substances - carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx).
The reduction catalyst is the first stage of the catalytic converter. It uses rhodium and platinum to help reduce nitrogen oxide (NOx) emissions.
The second stage of the catalytic converter is the oxidation catalyst. It reduces the amount of unburned carbon monoxide and hydrocarbons during their oxidation in the converter due to palladium and platinum.
There are two main variations of designs used in catalysts - ceramic and honeycomb. Most cars today use a honeycomb structure.
As for the third stage of the catalyst’s operation, it is based on a control system that monitors the flow of exhaust gases and uses this data to control the fuel injection system into the engine.
Malfunctions and causes of catalyst failure
- Mechanical damage (due to impact), resulting in destruction of the ceramic core.
- The use of low-quality fuel or deviations in the composition of the fuel-air mixture.
When using fuel with a high iron content, metal particles stop the neutralization reaction.
- An increased content of hydrocarbons in the exhaust (unadjusted engine) and an excessively lean mixture lead to a significant reduction in the service life of the catalyst.
They actually destroy it.
- Penetration of the lubricant into the exhaust tract entails baking of this lubricant on the working surface.
- As service station specialists noted, when using fuel with a high content of additives that can increase the temperature of the exhaust gases, the catalyst honeycomb may melt and fail.
- If the car is towed or pushed to start the engine, there is a risk of unburnt gasoline entering. In this case, an unwanted chemical reaction occurs that can lead to an explosion.
- Contact with cold water is no less detrimental. In the process of overcoming a water barrier, liquid can enter a body heated to 900 degrees Celsius.
Signs of breakdown
- The vehicle becomes “stupid”, the idle speed fluctuates, the car stops “pulling”, the dynamic characteristics deteriorate, the converter can become red hot (the catalytic converter is clogged, that is, the exhaust gas flow capacity is reduced).
- Characteristic rattling and ringing (the catalyst honeycomb has crumbled).
Consequences of catalyst particles
The catalytic converter has failed, can it be repaired?
If the catalyst fails, you will have two options to solve the problem:
- Purchase and installation of a new unit with a catalyst. Although this is quite expensive, you will not have any additional problems in the future, and air pollution will be at a minimum level.
- Alternatively, knocking out the old element, which entails the following consequences - an increase in fuel consumption as a result of changing the parameters of the exhaust tract, will require flashing the ECU, since as a result of removing the catalyst with oxygen sensors, a signal about a system malfunction will always be given (the "check" will constantly light up ").
The catalyst cannot be repaired. It can only be replaced with a universal or “native” one. It is also possible to replace the neutralizer with a flame arrester.
New catalyst, why is it so expensive?
Precious metals are used to produce the catalytic converter - platinum, rhodium, palladium. Therefore, the cost of the element is very high.
It is worth noting that the higher the category of sputtering, the more precious metals are used, that is, the higher the level of standards to which sputtering corresponds (Euro-2,3,4), the greater the amount of precious metals required for complete oxidation.
Cheap catalysts do not meet the required standards, as a result of which, when installing this element, the “check” will be constantly on.
Universal catalyst from folk craftsmen
Original catalysts are quite expensive, which forces car owners to look for other ways to solve the problem. Some people install a flame arrester on their car, while others prefer a universal catalyst.
https://www.youtube.com/watch?v=EdaXkFkV6Lw
In principle, universal catalysts are the same devices, only in a low price category. Like the original catalytic converters, they come in ceramic and metal.
The latter, however, are considered more durable.
Their operation follows exactly the same principle as original catalysts, so when using them there is no need to reflash the car’s on-board computer.
A significant disadvantage of universal catalysts is their short service life. Even “durable” metal units rarely work properly for more than two years.
Although, as practice shows, even this period is too long.
As a rule, already after passing the second technical inspection, the level of harmful substances in the exhaust gases exceeds the norm, which does not allow the vehicle to pass the technical condition control.
It happens that the neutralizer does not cope with the required task as a result of the fact that it cannot reach the required temperature. Therefore, when taking readings of the CO level, try to force it to heat up.
The catalyst can be brought into working condition by increasing engine speed, holding it at a high level (5500-6000 rpm) for several minutes.
Most often, after such an execution, the catalyst “wakes up”, with the help of which you can obtain the required level of exhaust.
Flame arrestor instead of catalyst
- To make a flame arrester, you will need two iron pipes, one of which should be the same in diameter as the exhaust pipe of the vehicle, and the other should have a large diameter, which will be the body of the flame arrester. In addition, we stock up on simple kitchen metal sponges.
Using regular kitchen sponges, fill the space between the pipes
- Next, we drill holes with a diameter of approximately three millimeters across the entire area in the inner pipe. Then it must be inserted inside the housing (i.e. another large diameter pipe). Now we brew one of the sides.
Firmly tamp the steel wool
- In the middle of the inner pipe we mount a washer, in which there should be a hole equivalent to ⅔ of the diameter of the smaller (inner) pipe. Ready flame arrester
- After this, we push metal washcloths between the two pipes (sort of like putting them on a pipe of a smaller diameter) and compact them tightly.
All space must be filled. You will need approximately 25 washcloths. Then we cut the free edge of the pipe with a large diameter, bend it and scald it.
Advantages and disadvantages of flame extinguisher
Advantages of a flame arrester:
- Increase in engine power.
- Warranty on the flame arrester (if you purchase a ready-made flame arrester, and not one made by yourself).
- High reliability.
- Long service life.
- Low cost.
Flame arrestor
Disadvantages of a flame arrester:
- The need for additional measures (installation of decoys, firmware of the control unit).
- Loss of vehicle warranty (for new vehicles).
- The levels of harmful substances in the exhaust gases will increase.
Lambda probe deception, how to deceive a lambda probe when replacing the catalyst with a flame arrester
Mechanical blend of the oxygen sensor
When removing the catalyst and installing a flame arrester, the lambda probe, which is located near the catalytic converter, will generate an error indicating its malfunction. In this case, disconnecting the oxygen sensor from the vehicle wiring will not solve the problem.
Therefore, you should either reprogram the oxygen sensor to the Euro-2 standard, or install an electronic or mechanical oxygen sensor simulator (controller, emulator). The snag restricts the flow of exhaust to the lambda probe and adjusts its operation, taking into account the changed operating conditions of the exhaust system.
But the effectiveness of its use is not one hundred percent, since not all cars can replace the functions of the oxygen sensor with a controller.
Pro tip: to install a flame arrester you need a qualified technician and system adjuster
Undoubtedly, you can make and install a flame arrester yourself, but even if this event is successful, you will still need a catalytic converter blende, as well as setting up the entire system. Therefore, it is better to entrust this to professionals in order to avoid problems with the exhaust system in the future.

Replacing the catalyst with a flame arrester
Home Catalysts Replacing the catalyst with a flame arrester
Can installing a flame arrester instead of a catalyst really solve the problem of a damaged part? Is it possible to say goodbye to your old device and avoid buying a new one? We will give answers to these questions in our article.
What is a catalyst and what functions does it perform?
Owners of modern cars think little about what a catalyst is, as they believe that it does not have much influence on the functioning of the car. On the one hand, this is the right idea, since the catalytic converter is installed in the car not before, but after the engine and serves as a place for processing exhaust gases.
Its function is to break down dangerous components. Inside the product there are honeycombs made of metal or ceramics, which are coated with catalyst substances. Most often, rhodium, platinum, palladium are chosen for these purposes, and less often gold.
The catalytic converter has a long service life, but like any other part, it cannot be considered eternal.
Constant use, violation of operating rules, mechanical damage - all this leads to product failure.
The operating features are such that when heated (it inevitably occurs in this part of the car), oxidation and breakdown of dangerous elements occurs. How can this affect the performance of the engine?
The bad news is that when the metal honeycomb becomes dirty or the ceramic melts, the catalyst turns not into a filter, but into a plug that interferes with the exhaust of gases.
As a result, the engine is subjected to extreme heat, which in turn leads to cracks and leaks. Not every driver can understand in time what is wrong and save the engine from harmful effects.
That is why you should know the signs of an impending breakdown.
Due to its characteristics, the catalyst becomes a device that allows you to convert exhaust gases. This makes them less dangerous to people and the environment.
It would seem that it is impossible to rid the car of such an important part. But buying a new product is expensive, and some cars have two catalysts installed. The craftsmen found a new opportunity - to replace the catalyst with a simple pipe of the same diameter.
From a savings point of view, this is an excellent solution. In fact, you will have to pay for this with the appearance of malfunctions in the future. After all, the heating temperature in the exhaust system will be too high.
Read more about replacing the catalyst with a flame arrester
In order to get to the catalyst and assess the extent of its damage, you need to dismantle part of the exhaust system and make a cut. This is the only way you can see how much the device has worn out.
Installing a flame arrester will help avoid unnecessary expenses. What are the features of the device and the process itself?
- The flame arrester does not split gases, but performs a resonating function.
- When using it, it does not matter how high-quality fuel the car consumes, since the device does not have honeycombs and does not clog.
- By adjusting the flame arrester to the dimensions of the previously installed catalyst, oxygen sensors do not notice the replacement. Still, in some cases it is necessary to install special “decoys”.
- The replacement steps vary depending on what product you want to install - purchased or homemade.
- Flame arrestors have a long service life, cool the system and do not affect engine operation.
- The downside of installing a flame arrester on a new car is that you void the manufacturer's warranty.
Now you know why a flame arrester is installed instead of a catalyst.
Get rid of your old part and get cash for it
Many drivers already know that they should not throw outdated catalysts in the trash. Our company has established a system for recycling these devices. You can even get money for a broken product!
We have been purchasing old catalysts on mutually beneficial terms for more than five years. We accept particulate filters, metal and ceramic catalysts, paying impressive sums. To start cooperation, contact us online or by phone.

Flame arrestor instead of a catalyst - pros and cons of replacement - Repair and tuning of mufflers in St. Petersburg
We welcome all readers, and today we want to discuss in detail the topic of replacing a catalyst with a flame arrester , and also dispel myths and rumors about prof.
unsuitability and other tales from the Internet and forum threads.
Let's start with the basics and immediately explain what a flame arrester is, what it is made of, how it is installed, how long it lasts, how much it costs, what it is eaten with and other information regarding this mysterious device :)
What is a flame arrester?
Flame extinguisher is a device for extinguishing the temperature of exhaust gases and reducing their resonance. Literally, the flame arrester very effectively reduces the temperature of the exhaust gases, and also acts as a primary resonator.
Flame arrestors are divided into manifold (installed in the exhaust manifold block) and free-standing (installed on a straight line or exhaust pipe). They come in several shapes: round, oval and turbine.
In life it is called briefly and clearly - “flame gas”
Design and material of the flame arrester
– The flame arrester device is structurally similar to a conventional muffler resonator. In the simplest case, it is a small-diameter pipe with holes for gases (perforations) that is inserted into a steel casing.
A heat-resistant filler, for example, basalt wool, is laid between the body and the pipe, which additionally dampens sound waves. The flame arrester has an inlet and an outlet (do not be confused during installation!), the end sides are tightly welded or wrapped.
The sizes of flame arresters depend on engine power and have different diameters, lengths and center offsets.
– The design of more advanced flame arresters has diffusers (funnels) designed to more effectively reduce the speed of the gas jet.
It is important that the body of the flame arrester is two-layer, with filler - this will reduce the noise level (and eliminate metallic ringing under the bottom), and the metal from which it is made has high resistance to deicing agents.
For example, in the production of Sprint flame arrester housings, aluminized steel is added, while in MG-Race flame arresters, high-alloy stainless steel is added, hence the difference in the price of flame arresters, and the latter lasts almost until the death of the engine.
What is the service life and operation of the flame arrester?
The average lifespan of a free-standing stainless steel flame arrester ranges from 5 to 10 years. Collective flame arresters last a little less (3-5 years), since they are located directly in the “hottest” place.
I would like to note that the flame arrester itself is practically not destroyed; the welds and exhaust pipes suffer.
For example, if you take an MG-Race flame arrester installed in a stainless steel line and welded in an argon environment, then the service life of such a structure will be tens of years.
If you install a conventional flame arrester made of aluminized steel and weld it with an iron exhaust pipe in a CO2 environment, then naturally the service life will be shorter. It is also worth taking into account the operating climate, the health of the engine and, of course, mechanical impacts (shocks, scuffing, etc.).
Pros and cons of a flame arrester in a muffler system
So, since initially we are installing a flame arrester as an alternative to a very expensive original catalyst, we will argue from the point of view of the budget, or rather its savings. Naturally, by installing a flame arrester in the exhaust system, we want to save a lot and we do it successfully 🙂 this is your first plus.
After installing the flame arrester, you don’t have to think that by filling up with bad gasoline, you can “put down” an expensive catalyst - that’s your second advantage.
Oddly enough, the flame arrester has a direct-flow structure, rather than the dense honeycomb of the catalyst, which contributes, although not greatly, to an increase in engine power - here’s your third plus.
Of the minuses , and believe me, you can’t go anywhere without them:) – this is environmental pollution, exhaust gases are not cleaned in any way and exit into the environment as is (stench + soot).
And another disadvantage is the increased load on the muffler components located behind the flame arrester (resonators, rear banks, muffler pipes), they are exposed to high temperatures and fail faster. Here are the pros and cons of replacing the catalyst with a flame arrester.
There are still more advantages, but it’s definitely up to you to decide whether to install a cheap original catalytic converter unit (catalyst) or a flame arrester.
How to install a flame arrester
Almost any flame arrester is installed in the exhaust gas exhaust system using electric or gas welding.
Therefore, you probably won’t be able to install a flame arrester yourself in a garage without welding equipment, even if you repair everything yourself.
The installation options for manifold and free-standing flame arresters differ, since to install a manifold flame arrester, you need to remove the exhaust manifold, which is not required to install a flame arrester on the exhaust pipe.
How much does it cost to install a fire extinguisher?
The cost of the procedure for installing a flame arrester directly depends on its location and the brand of the manufacturer. On average, the price in St. Petersburg for installing a manifold flame arrester (with removal of the exhaust manifold) varies from 6,000 rubles. up to 8000 rub. To install a separate flame arrester, the cost will be from 3,000 rubles to 5,000 rubles.
What else do you need to know when installing a flame arrester?
If you decide to replace a failing catalyst with a flame arrester, you should know that some cars have devices (oxygen sensors or lambda probe) for taking readings of the output of purified gases from carbon dioxide (CO2) and when removing the catalyst from the system, they will incorrectly adjust the fuel supply . In this case, you need to either install a mechanical lambda probe with a minicatalyst , or programmatically convert the engine control unit to Euro-2 standard (that is, flash or do chip tuning )
We hope that this article will give you objective and complete information on the general perception of such a device in the exhaust system as a flame arrester. Thank you for your attention and interest, sincerely. auto repair and tuning service for mufflers “GlushakoFF”

Flame arrestors
The flame arrester is an affordable replacement for the catalyst. Unlike a catalyst, it does not have a service life and performs all the same functions, except for reducing the concentration of CO and CH in the exhaust gases. Do not confuse a flame arrester with a direct-flow system! Replacing a catalyst with a flame arrester does not increase the noise level of the machine (provided that certified products are used).
It is impossible to accurately predict the moment of breakdown of a catalyst (car converter or neutralizer).
While other replaceable car parts such as the timing belt, filters or spark plugs can be changed based on the vehicle's mileage, the catalytic converter may need to be replaced at any time.
Its service life is greatly influenced by the quality of the fuel, the condition of the engine and the ignition system. Considering that the cost of a new spare part starts from 30 thousand rubles per piece, the desire of many car owners to one day solve all the problems with this unit becomes understandable.
Very often, the problem of replacing a catalyst is solved by installing a pipe cut instead. Another makeshift option is to remove its contents (only the empty body remains). In both cases, after such repairs, an unpleasant sound will appear, and the thin walls of the case without ceramic honeycombs can quickly burn out.
Replacing the catalyst with a flame arrester
Almost all car enthusiasts have heard of a flame arrester, however, few have decided to install it instead of a catalyst. There is a misconception that this will increase the overall noise level of the car.
Modern models are resonators (silencers) in design and consist of several chambers. This is exactly how most products from SPRINT, Fox, AWG or MG-Race work.
MG-Race models additionally have a layer of silica fiber, which dampens engine noise very well. As a result, its overall level when installing a flame arrester instead of a catalyst is significantly reduced.
Another problem that many see when installing a flame arrester lies in the difficulties when passing a vehicle inspection. Let us immediately clarify that the previous regulations for passing technical inspection in our country have long been abolished, and when receiving (purchasing) a diagnostic card, no one will be interested in the presence of a catalyst in the car.
In Russia, there are fairly lenient standards for the content of CO and CH in exhaust gases. Even a properly functioning Zhiguli or Volga engine (which until recently was sold without any gas neutralizers) easily “passes the environmental test.”
Some technical centers offer to make a flame arrester based on the body of the old catalyst. This method is usually called “stuffing”. Repairs according to this scheme are usually used to reduce the overall cost of work, which does not have the best effect on their quality.
Our company installs flame arresters for any foreign cars with different engine displacements. An additional advantage of such “tuning” of the exhaust system is a small (5-10%) increase in engine power and torque.
Additional horsepower and newton meters appear due to a freer exhaust - exhaust gases no longer encounter an obstacle in the form of thin catalyst channels.
At the same time, the noise level does not increase, and the CO and CH content, provided that the engine is working properly, fully satisfies Russian standards.

Replacing the catalyst with a flame arrester in Moscow at a low price in Ramflow
Replacing a catalyst with a flame arrester is an opportunity to save money, reduce engine noise and the load on the exhaust system. The work requires competent selection of spare parts, welding and related activities (installation of blende and ECU firmware).
Therefore, it is better to entrust it to the masters of the RamFlow exhaust systems center in Moscow. The cost of installing a flame arrester instead of a catalyst starts from 1,500 rubles. We have our own warehouse of spare parts, an argon welding machine and provide a guarantee for the work.

A flame arrester is a catalyst substitute that slows and cools exhaust gases. The main requirement for it is anti-corrosion properties and strength.
The flame arrester is selected individually for each vehicle. Installation of decoys may also be required.
Therefore, if you want to install a flame arrester instead of a catalyst, then contact the professionals.
custom exhaust
The car service has its own equipped production facility.
The best grades of titanium and steel are used to produce an exclusive exhaust system.
Advantages of installing a flame arrester instead of a catalyst
The price of original catalysts starts from 20,000 rubles. Therefore, the main advantage is the opportunity to save significantly. The advantages of such a replacement also include:
- the ability to use gasoline with a lower octane number. The catalyst will no longer clog, so you can further save on fuel;
- increase in engine power. Stock catalysts reduce engine power by 5-7%. This is due to their cellular structure, which inhibits exhaust gases. After replacement, the used exhaust will not encounter resistance along the way;
- Solving catalytic converter problems in the long term. The service life of catalytic converters does not exceed 300,000 km in Europe. In Russia this figure barely reaches 150,000 km. Therefore, if you cut out the catalyst and install a flame arrester, you will save yourself from the need to periodically clean, rinse and replace the filter.
Note that rumors that removing the catalyst leads to rapid failure of the muffler, engine wear and an excessive increase in exhaust toxicity are myths. There are practically no downsides to installing a flame arrester.
