CTS Turbo is proud to announce the release of our downpipes for BMW F80/F82 M3/M4. Our stainless steel high-flow downpipes allow for faster spool, better transient boost response, higher boost and great sound. Our downpipes are the first part of our modular exhaust system and are compatible with factory mid pipes and our upcoming CTS Turbo mid-pipes. You should expect 27whp/40ftlbs torque gains when paired with appropriate tuning software. We used CAD simulation to streamline the flow of exhaust gasses and ensure seamless integration with factory and CTS exhaust components. 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 upgraded software because most CEL deletes or emulators are not compatible with these cars.
