NOT SO FUN FACT:

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!

THE EVM SOLUTION:

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.
  • No cutting wires, no damage to factory cables, fully reversible.

Included:

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

Fitment:

• W463 - G 550 MY2018+

Note:

• *Before Placing Order, Confirm If Your Car Is Equipped with Factory Exhaust Valves*
• The RENNtech EVM is placed in the trunk, no hard wiring necessary.
• For extra convenience, the EVM is programmed so once the exhaust valves stay fully open in Position 1 (Button 1). Valves will stay open even when the car is turned off and restarted. The EVM will ONLY revert to factory setting by pressing Button 2.

RENNtech has become the premier Mercedes-Benz specialist and Hartmut Feyhl himself is regarded by many as USA’s foremost authority in Mercedes tuning. His vast experience comes from 12 years spent at AMG Germany before serving as the North American division’s Technical Director. Prior to the tuning company’s merger with Mercedes-Benz in 1999, by the request of AMG Germany, Feyhl branched out on his own to start RENNtech and service the existing AMG North America customers.

Performance without compromise. This is the foundation upon which we have built our reputation. Established in 1989 by Hartmut Feyhl, RENNtech has evolved and grown from servicing AMG’s customers into the foremost authority on tuning and customizing AMGs and Mercedes-Benz. RENNtech also offers tuning solutions for Porsche, Audi and Bentley vehicles, along with other European luxury cars.

Over the years, we have developed high-performance products for virtually all Mercedes-Benz AMG vehicles. Some of the most notable among these are the 200 mph RENNtech E7.4RS (which claimed ‘Fastest Sedan in the World’ honors by Car and Driver Magazine in 1996) and the more recent 945 LB-FT 5.5L V8 Biturbo RENNtech R3+ Monster. Each of these vehicles are just a sampling of what RENNtech has achieved, featuring extreme performance, upgraded aesthetics and a fit and finish that rivals factory vehicles.
