If your car is equipped with factory exhaust flaps, with or without a center console button to open or close them, factory settings doNOTallow the flaps to fully open unless certain speed and/or RPM have been reached. For example, while cruising the exhaust flaps will never fully open!
THE EVM SOLUTION:
RENNtech’s plug & play EVM Exhaust Valve Module allows you to open the exhaust flaps of your car 100% at all times by pressingButton 1on the remote control. If you wish to go back to factory settings simnply pressButton 2. This gives you complete control over the exhaust sound and rumble of your car at any time regardless of speed, RPM or driving mode!
The RENNtech Exhaust Valve Module is made in Germany.

The RENNtech EVM is placed in the trunk and needs to be hard wired to the exhaust flap
For extra convenience the EVM is programmed so once the flaps are fully opened they will stay that way even when the car is turned off and restarted later hence no need to press button 1 over and over every time you start the car. It will ONLY go back to factory setting by pressing button 2.
