This small plug-and-play unit connects into the factory wiring harness and allows the driver full control of the exhaust valve whenever they want. For too long enthusiasts have had to pay too much for command of their exhaust. We solve that issue. These controllers connect to the vacuum solenoid in the trunk to provide the driver control over their exhaust flap. Before purchasing please ensure your car has a VACUUM style exhaust valve. These DO NOT fit on electronic valves.

100% REVERSABLE, ALWAYS ABLE TO RETURN TO STOCK AT ANY TIME

In regards to fitment, many BMWs have the exhaust flap and our controller can be used. In the pictures below you will find the control unit. If your car has this, then this product will fit your car.
