The downpipe (also called the decatalizer) is a fitting that fits between the turbine and the exhaust.

To obtain better performance it is essential to replace the original catalyst with a sports car that allows a better flow of exhaust gases with a whole series of advantages that you can see below.

If you have mapped the ECU, the downpipe is a highly recommended component to get even more power from your engine without further stressing it.

In fact, with the open downpipe, even without increasing the turbine or injector pressure, a natural increase in power is obtained up to 10/12% more.

If the car is remapped, this increase is even more remarkable and helps to achieve maximum performance after the ECU is remapped or after the installation of a larger turbine.

The advantages of ours Downpipe (decat):

Mounting a InoxPower downpipe allows you to obtain numerous advantages in addition to increasing power and torque, such as a better throttle response, since the exhaust gases flow out much more quickly as they are not blocked by the catalyst that suffocates the passage.

This also allows the turbine to overheat less, guaranteeing a lower temperature of the exhaust gases which, flowing more quickly, concentrate less close to the turbocharger, also decreasing the back pressure.

Last but not least, the free downpipe ensures an incredible sound that becomes darker and more aggressive than the original system.

The original catalyst absorbs the sounds, also having the function of silencer and the installation of the downpipe ensures a clear improvement in the sound of your car even with the rest of the original exhaust.

To summarize, by mounting the InoxPower downpipe you will get:

- better performance

- quicker engine response

- sound racing

- reduction of the turbo temperature

Eco-line

ECO-LINE is the economic version of the WWW.INOXPOWER.COM EVO-RACE downpipes.

Let's be honest, this is a less beautiful version of our EVO-RACE downpipe, the best downpipe for BMW you will ever have.

With the ECO-LINE downpipe we have aligned ourselves with what is the media offer that you find online.

This way you have two choices. Fit the EVO-RACE downpipe, the best there is for your BMW, or save with the ECO-LINE model, which is similar to the products you find at this price.

What have we given up to cut the price?

It was easy, we used less noble materials. So no INOX!

We saved money on metal welding and finishing, all of which are extremely expensive.

In this way we have created a product for the customer that cares about the price.

What have we not given up on instead?

To the study of flows! The ECO-LINE downpipe is less beautiful, less resistant and less finished than the EVO-RACE model, but maintains the same basic design to guarantee you the maximum performance of your BMW.
