Get full control of the your BMW M3

Flaps fully open, closed or automatic factory control

The CARGRAPHIC valve control unit type is installed between the exhaust valves and the standard control unit. It thus takes over complete control of the factory valves. This allows the flaps to be opened or closed manually by remote control and even reactivates the factory automatic control.

Quiet engine start possible

For the BMW M3, we offer a vehicle-specific valve control system that makes installation simple and easy, as well as allowing trackless refitting. A special feature is the possibility of a "quiet" engine start: For BMW models with two electric exhaust valves, the CARGRAPHIC flap control system allows the valves to be closed after the ignition is switched on, before the actual engine start. This makes starting the engine, which is otherwise very noisy, acoustically much more restrained and neighbour-friendly.
