1. First of all, ecology.
  2. If you are proud that your car doesn’t pollute environment, then after replacing the converter unlimited with a substitute, you need to stop doing this, because your car will no longer have Euro-4 or Euro-5 standard.
  3. No need to program car computer. Vehicle electronic control system is designed to use a converter unlimited and without it will start to go crazy. Using a substitute, you need to invent tricks on oxygen sensors, and in the best case, reprogram the engine.
  4. Reducing the resource of the exhaust system.
  5. Even a good  converter unlimite substitute with the task of lowering the temperature of exhaust copes worse than the converter unlimited, so the risk that the muffler burns out increases.
  6. On the other hand, you can change more than one silencer for money that will save a flash suppressor.

If the benefits of replacing  converter unlimited with a flame arrester are obvious for you, then a detailed instruction of step-by-step process will be useful.

Usually, car owners have to deal with universal flame arresters, which must be adjusted locally or even make such a unit on their own. People without experience with a grinder and welding should not take up the replacement.

Step 1. Removal of the converter unlimited

The catalyst and collector are located directly in the exhaust manifold. converter unlimited is easier to remove, especially if the design permits using a screwdriver.

If there is no such a possibility,

The second one requires dismantling the exhaust manifold, which increases the complexity of the process.

Step 2. Choosing a flame arrester

The supply of such car parts is sufficient, you can consider the details, cost, and other elements. In general, the main thing is that it is two-layer, the brand is not so important.

However, this is such a simple unit that you can do it yourself. Cut the casing from the catalyst, knock out the entire filling from it, and instead insert a piece of perforated pipe, cover the casing from the inside with heat-resistant, sound-absorbing material, brew, and the arrester is ready.

As for cost, such an assembly will turn out to be very cheap, but only those who know how to use a welding machine should undertake independent manufacture of a flame arrester. As practice shows, the most popular damage to a flame arrester is a burst weld.

Step 3. Installing a flame arrester instead of a converter unlimited

If we are not talking about products that are precisely designed for regular places, then to install a converter unlimited substitute you have to use a combination of welding and ingenuity.

It&rsquo’s not that it’s very difficult, but you have to measure and adjust the dimensions, think over the location, especially when it comes to collector arresters.

In addition, no manufacturer describes such a procedure in official reference materials, so you need to look for information in additional sources.

Step 4. Correction of electronics

For the car to work correctly without converter unlimited , you need to consider reprogramming for the second lambda probe or completely reflash the motor.

deception is like a converter unlimited in miniature,

it “filters” a piece of exhaust that enters the sensor, showing that everything is fine,

the emulator simply transfers the values ​​that it expects to the engine, without real measurements.

Deceptions and emulators may not work, but a good alternative firmware almost always solves problems after installing such a device.

What is the general cost to replace the converter unlimited  with a flame arrester?\

Units themselves are relatively inexpensive from 15 to 20 USD, depending on the brand and design. Prices for converter unlimited replacement services depend on region and brand of car.

The average price would be 75-100 USD for such a service (although the price range is very large). Separately, you will need to pay extra for installing a lambda sensor and reprogramming.

Talking about converter unlimited its starting cost will get even up to 1200 USD, which is not a limit, due to various car models.
