BMW S58 G80/G82 M3/M3 Competition/M4/M4 Competition Downpipes. These stainless steel downpipes provide faster scavenging, better boost response, higher boost, and a great sound. These downpipes are the first part of our modular exhaust system and are compatible with the factory midpipes. You can expect significant torque gains when used with suitable tuning software. We used CAD simulation to streamline the exhaust gas flow and ensure seamless integration with both the factory and CTS exhaust components. Numerous hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound.

• Durable 304 food-grade stainless steel
• Laser cut flanges
