Overview

From the factory, the exhaust valves on the 2019-2023 CLS 450 only open fully at certain speeds and rpm, even with the sport exhaust selected. The RennTech Exhaust Valve Module (EVM) hands that decision to you: one button on the remote opens the valves fully at any speed, the other returns control to the car.
