EVM - Exhaust Valve Module (Remote Controlled)



If your Mercedes-AMG is equipped with factory exhaust valves, 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 Exhaust Valve Module, (EVM) gives you complete control over the exhaust sound of your exhaust regardless of speed, RPM or driving mode! The Exhaust Valve Module allows you to fully open the exhaust valves of the AMG Sport Exhaust by pressing Button 1 on the remote control, and to return to factory settings by pressing Button 2.

The RENNtech Exhaust Valve Module is made in Germany.

Advantages of RENNtech’s EVM:

  • Activation completely independent regardless of drive mode
    • 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.
