High-flow stainless steel downpipe for the Audi RS3 8V/8Y and TTRS 8S with the 2.5 TFSI EVO (EA855) engine. Designed to remove the restrictive factory primary catalytic converters.
The downpipe is part of the CTS Turbo modular exhaust system and is compatible with factory or CTS Turbo centre exhaust pipes.
A CAD simulation model was used to optimise exhaust gas flow and ensure even flow distribution to the two outlets. The product was developed with precise fitment, efficient exhaust gas flow and a distinctive sound.
After installation, the Check Engine Light will illuminate. Stage 2 software is required to prevent the light from coming on, as CEL clearing or emulator solutions are not compatible with these vehicles.
