CTS Turbo BMW S58 G80/G82/G87 M2/M3/M3C/M4/M4C High-Flow CATS

CTS Turbo introduces high-flow cat downpipes for the BMW S58 G80/G82/G87 M2/M3/M3C/M4/M4C. These stainless steel downpipes deliver faster spool, better transient boost response, higher boost, and great sound. As the first part of CTS's modular exhaust system, they are compatible with factory mid-pipes, and you should expect strong torque gains with appropriate tuning. CAD simulation streamlined exhaust flow and ensured seamless integration with factory and CTS components, with many hours of R&D spent on perfect fit, smooth flow, and excellent sound.
