RennTech Exhaust Valve Module 2019-2024 Mercedes-AMG GT 63 4-Door X290

From the factory, the AMG performance exhaust on the X290 GT 63 4-Door keeps its valves partly shut at cruise, whatever drive mode or exhaust button you pick. They only swing fully open at certain speeds and rpm. The RennTech Exhaust Valve Module (EVM) takes that decision away from the car: press button 1 on the remote and the valves open fully, press button 2 and the factory logic is back in charge.

Fitment notes

For the X290 AMG GT 63 and GT 63 S 4-Door Coupe with factory exhaust valves. RennTech lists these cars from MY2019 on; the table runs to the final X290 model year. The GT 43 and GT 53 4-Door also take this module but only when ordered with the optional performance exhaust. Your VIN is required with the order so RennTech can match the harness.
