Valvetronic Designs Exhaust Valve/Flap Controller – BMW Vacuum-Valve Models

OVERVIEW

This small plug-and-play unit connects into the factory wiring harness and gives the driver full control of a factory vacuum-actuated exhaust valve at the touch of a button. The controller connects to the vacuum solenoid in the trunk to provide direct control over the exhaust flap, letting the driver switch between quiet and open exhaust modes without relying on the car's own drive-mode logic.

Before purchasing, confirm your car has a VACUUM-style exhaust valve — this controller does not fit electronic valve systems. Installation is plug-and-play and fully reversible; the car can always be returned to stock at any time.
