CTS Turbo BMW F90 M5/M5C & BMW G15/G16 M8/M8C RACE DOWNPIPE SET

CTS Turbo's race downpipe set is purpose-built for BMW F90 M5, M5 Competition, and G15/G16 M8, M8 Competition models equipped with the S63 twin-turbo V8. This complete replacement system eliminates the factory catalytic converters, dramatically reducing exhaust back pressure and freeing up the twin-turbo setup. Precision-engineered from high-grade stainless steel, each downpipe features smooth mandrel bends and CNC-machined flanges for optimal fitment. Designed for motorsport and track applications where emissions compliance is not required. Professional installation and ECU calibration essential to maximise results from this unrestricted exhaust path.
