CTS Turbo is proud to announce our own high-flow downpipe for the 2018+ Audi 8V/8Y RS3/8S TTRS with the 2.5L TFSI EVO (EA855) engine. This stainless steel high-flow downpipe allows the user to remove the restrictive factory main catalytic converters. This downpipe is part of our modular exhaust system and is compatible with both the factory and CTS Turbo mid-mufflers.

We used CAD simulation to optimize the exhaust gas flow and ensure it splits evenly into two outlets. Many hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound. Unfortunately, the Check Engine Light will come on after installation; we strongly recommend using "stage 2" software, as CEL deleters or emulators are not compatible with these cars.

• Large 4.0" downpipe exhaust that splits into dual 2.5" pipes
• Durable 304 food-grade stainless steel
• Laser cut flanges and precision milled V-band
• Factory-style 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 center mufflers
• Aggressive sound – really makes that 2.5T scream
• No drone under normal driving conditions
• Optional drive shaft removal tool available separately
• Stage 2 software is required to avoid the check engine light.
