If your car is equipped with factory exhaust flaps, with or without a center console button to open or close them, factory settings do NOT allow 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!


RENNtech’s plug & play EVM Exhaust Valve Module allows you to open the exhaust flaps of your car 100% at all times by pressing Button 1 on the remote control. If you wish to go back to factory settings simnply press Button 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!

Advantages of the RENNtech EVM

    Override your cars factory exhaust flap setting with the push of a button.
  • EVM does not engage with CAN-Bus
    No interference with any control units.
    Software updates do not interfere with the functionality of the EVM exhaust valve module.
  • Plug and Play with original plugs
    No cutting wires, no damage to factory cables, fully reversible.


  • 1 x Exhaust Valve Module
  • 2 x Remote Controls (Button 1 fully open, Button 2 back to factory)
  • Wiring harness (model specific)
  • Installation manual


  • No special tools or modifications required for installation
  • 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.
