Get full control of your Porsche 911 991.2 Speedster 4,0l with OPF exhaust valves

Flaps always open, closed or automatic factory control

The CARGRAPHIC valve control unit is installed between the electronic valve actuators and the factory control unit. It thus takes over complete control of the  valves either from the standard exhaust system or integrated in CARGRAPHIC exhaust components. This allows the flaps to be always opened / closed manually by remote control or reactivates the factory automatic control.
 

Quiet engine start possible

For the Porsche 911 991.2 Speedster 4,0l with OPF, 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: The programmable start mode allows the engine to be started either with the flaps open or closed, as desired. The control unit either remembers the last mode used or you simply programme the desired flap position permanently.
