CTS Turbo BMW S58 G80/G82/G87 M2/M3/M3C/M4/M4C Downpipes

CTS Turbo brings serious flow to the S58 with downpipes for the G80/G82/G87 M2/M3/M3 Competition/M4/M4 Competition. The stainless steel downpipes deliver faster spool, better transient boost response, higher boost and great sound. As the first part of the CTS modular exhaust system, they are compatible with factory mid-pipes — and with appropriate tuning software you can expect strong torque gains. CAD simulation was used to streamline exhaust flow and ensure seamless integration with both factory and CTS components, with many hours of R&D spent on fit, flow and sound.
