EVM - Exhaust Valve Module (Remote Controlled)
NOT SO FUN FACT:
Mercedes-Benz and AMG cars equipped with factory exhaust valves, with or without a center console button to open or close them, the factory settings do NOT allow the valves to fully open unless certain speed and/or RPM have been reached. For example, while cruising the exhaust valves will never fully open!
THE EVM SOLUTION:
By pressing Button 1 on the remote control, RENNtech’s Exhaust Valve Module (EVM) allows you to open the exhaust valves 100% at all times. If you wish to go back to factory settings simply press Button 2. This gives you complete control over the exhaust valves regardless of speed, RPM or driving mode, adding sound and rumble to your car.
Advantages of RENNtech’s EVM:
You need to get this!
Car sounds great at idle and better when driving, sounds much cleaner now.
A must have upgrade!
Solid product. Quick and easy insulation. Took less than five minutes once I remove trunk liner. At idle and cruising at low RPMs sounds like a different car altogether. Revving the car in neutral sounds better as well but the rev limiter I think is keeping it a bit tamer than it actually is when accelerating hard. Very happy with purchase overall
