We have developed a valved system for the F90 that will put a smile on your face no matter the occasion. The F90 M5 system measures 3 inches from inlet to outlet.
The system runs back to electronically-controlled exhaust valves that can either be tied into the cars' ECU system to be controlled via the Sport and Sport+ settings, or run on a separate system so you can have command regardless of the drive mode.Â
