CTS Turbo is proud to announce our proprietary high-flow downpipe for 2017+ Audi 8V RS3/8S TTRS with 2.5L TFSI EVO (EA855) engine.

This stainless steel high-flow downpipe that allows the user to remove the restrictive factory “main catalytic converters”. This downpipe is a part of our modular exhaust system and it is compatible with factory or CTS Turbo mid-pipes.

We used CAD simulation to streamline the flow of exhaust gasses and ensure that it splits evenly into two outlets. Many hours of R&D were spent to ensure perfect fit, smooth exhaust flow and excellent sound.

Unfortunately, the Check Engine Light will come on after the installation; we strongly recommend using “stage 2″ software because the CEL deletes or emulators are not compatible with these cars.
