MBS G90 / G99 Catless Race Downpipe

(BMW G90 M5 | G99 M5 Touring – 4.4T V8)

Unlock the full performance potential of your next-generation M5 with our Catless Race Downpipe, engineered to significantly improve exhaust flow, turbo efficiency, and overall power output. Designed specifically for the 4.4L twin-turbo V8 platform, this system reduces backpressure and allows the turbos to spool faster, resulting in increased horsepower, torque, and a more aggressive exhaust tone.

Featuring a large-diameter high-flow design, this downpipe maximizes airflow while delivering a raw, race-inspired sound. This upgrade is ideal for performance builds looking to push the limits of the G90/G99 platform.
