Bomiz BMW F90 M5 Valved Exhaust System
The Bomiz Valved Exhaust System brings out the full potential of the F90 M5’s twin-turbo V8. With the valves closed, it offers a controlled, refined tone ideal for commuting or cruising. Open them up, and the system delivers an aggressive, high-volume sound that unleashes the true character of the S63 engine.
Built from TIG welded 304 stainless steel, this system bolts directly to the downpipes — no cutting, no welding. Reuses your OEM valve motors or upgrade to Bomiz actuators for seamless control through factory drive modes.
