RennTech Exhaust Valve Module For Mercedes-Benz X156 GLA45 AMG 2014-2021

Description: RennTech plug & play EVM Exhaust Valve Module allows you to open the exhaust flaps of your car 100% at all times by pressing Button 1 on the remote control. If you wish to go back to factory settings simnply press Button 2. This gives you complete control over the exhaust sound and rumble of your car at any time regardless of speed, RPM or driving mode. The RennTech Exhaust Valve Module is made in Germany. If your car is equipped with factory exhaust flaps, 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. Attention: No special tools or modifications required for installation The RennTech EVM is placed in the trunk and needs to be hard wired to the exhaust flap For extra convenience, the EVM is programmed so once the flaps are fully opened they will stay that way even when
