CTS Turbo is proud to aounce our new single 3.5 High-Flow CAT for 2018+ Audi 8V/8Y 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.

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.

Y pipe included for fitment with factory exhaust.

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.

Single 3.5 race downpipe
Durable 304 stainless steel- Laser cut flanges and precision machined v-band
Factory-like placement of O2 sensors

Fitment:
2018+ Audi 8V/8Y RS3 2.5T EVO (EA855)
