Thorough long term street testing has confirmed that AWE's high flow downpipe, whether equipped with with the 400 cell ceramic catalytic converter (for FSI) or the 200 cell metal catalytic converter (for both FSI and TSI), will not set a Check Engine light or any fault codes in the ECU. For FSI customers looking for ultimate power, AWE's HJS German made metal catalytic converter will provide an additional 9hp over their ceramic converter option.

The NEUSPEED hi-flow downpipe is all stainless steel: flange, pipe, catalyst and flex joint! We improved on the factory design by opening the diameter to 80mm after the turbo and 70mm after our new hi-flow cat for a perfect match to our new 70mm exhaust system.
