CTS TURBO 3″ STAINLESS STEEL DOWNPIPE BMW S55 F80 F82 F87 M3/M4/M2 COMPETITION CTS-EXH-DP-0025

CTS Turbo is proud to announce the release of our downpipes for BMW F80/F82 M3/M4/M2 Competition 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 the factory and CTS exhaust components.  Many hours of R&D were spent to ensure a perfect fit, smooth exhaust flow, and excellent sound. Use of Bootmod3 software compatible with downpipes is strongly recommended. CEL will illuminate if correct software tuning is not used.
