Compatible with N20
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 5/6% 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 downpipe you will get:
- better performance
- quicker engine response
- sound racing
- reduction of the turbo temperature
The downpipe EVO-RACE you buy up www.inoxpower.com they are made of AISI 304 steel with TIG welding and brushed finish, to guarantee a perfect and aesthetically pleasing result. They are simple to mount designed to fit perfectly with the original OEM system (always check before buying if the Downpipe is compatible) or with the aftermarket exhaust.
