A Control Module is included with all systems, which can be used with the included remote control. Simply set to automatic, open and close modes.

CLOSE mode It helps the induction of car exhaust backpressure and increases torque at low rpm.
OPEN mode A free flow exhaust can bring Formula 1 sound and increase more horsepower at high rpm.
AUTO mode This mode will enable automatic open and close of the valves based on each car owner’s individual preferences and driving habits.In this mode, you can set the valve to open and close by detecting various signals, such as boost, depth of gas pedal, rpm, etc.
