CTS Turbo BMW S58 F97/G01 X3M/X3MC & F98/G02 X4M/X4MC Downpipes

CTS Turbo's downpipes are precision-engineered for the S58 twin-turbo straight-six in F97/G01 X3M and F98/G02 X4M variants, including Competition models from 2019 onwards. These mandrel-bent downpipes replace the restrictive factory components to improve exhaust gas velocity and reduce backpressure. The result is sharper throttle response and a more aggressive exhaust note. Designed for dealers fitting high-performance BMW applications, they integrate with factory mounting points and sensor provisions for professional installation across the X3M and X4M platform.
