Description
TM Performance F82 M4 Downpipe is the ultimate solution for improving power, throttle response, and exhaust note on your S55 powered M4. Our goal for the F82 M4 Downpipe was to provide a solution that would maximize power and torque, fit perfectly, and sound extraordinary. Our F82 M4 Downpipe relieve the stressful back-pressure caused by high-boost tunes, allowing the exhaust to flow freely, increasing power and torque, all while extending the longevity of your S55's turbochargers.
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 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 the factory and TM Performance exhaust components. Many hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound.
Elimination the stock restrictive catalytic converters provide a huge increase in exhaust flow and allow for a significant power gain today!
