CTS Turbo 8V/8Y RS3 and 8S TTRS 2.5T EVO RACE Downpipe

CTS Turbo is proud to announce our proprietary high-flow downpipe 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". 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. Features: - Large 4.0" downpipe outlet splitting into dual 2.5" pipes - Durable 304 food-grade stainless steel - Laser cut flanges and precision machined v-band - Factory-like placement of O2 sensors - Designed using the latest 3D scanning technology - Exhaust flow simulated with CAD software to ensure optimal flow routing - Perfect fit with factory or aftermarket mid-pipes - Aggressive sound - really makes that 2.5T scream - No drone under normal driving conditions - Optional driveshaft removal tool available separately Fitment: - 2018+ Audi 8V/8Y RS3 2.5T EVO (EA855) - 2018+ Audi TTRS 2.5T EVO (EA855) Stage 2 software is required to avoid check engine light.
