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