Valvetronic Designs BMW Exhaust Valve/Flap Controller - Vacuum-Valve BMWs
This small controller connects into your BMW's factory wiring harness and gives you full, on-demand command of the exhaust flap whenever you want it, without paying for a full aftermarket exhaust. It ties into the vacuum solenoid mounted in the trunk area to open and close the factory valve on command.
The install is plug-and-play with no cutting, splicing, or permanent changes to the car, and the connection is fully reversible, so you can return to a completely stock setup at any time.
Important Compatibility Information
This controller only works with BMWs that use a VACUUM-style exhaust valve. It will not function on electronic exhaust valve systems. Many BMWs share this factory vacuum flap across the 1, 3, 5, 6, 7 Series and X/Z models of the mid-2000s through mid-2010s, but confirm your car has the vacuum-actuated control unit before ordering.

Frequently Asked Questions
Will this work on my BMW's electronic exhaust valve?
No. This controller is built exclusively for vacuum-actuated exhaust valves and will not function on electronic valve systems.
Is the installation permanent?
No. The controller is fully reversible, so you can disconnect it and return the car to a completely stock exhaust valve setup at any time.
Do I need to modify my exhaust to use this?
No modification is required. It connects into the existing factory wiring and vacuum solenoid to control the valve that's already on the car.
