Control your exhaust volume with a remote control or a phone app. The Sound Kit takes the place of the factory exhaust valve control, which is usually through the engine computer. Instead, the exhaust flap can be opened or closed via a remote control or an app on your iOS or Android device. Open the valve(s) for louder exhaust note. Close the valve(s) for quieter operation. This can be a huge bonus for extended highway driving by closing the valve and muting the exhaust noise considerably. Installation will disable the factory control but can be reversed or removed at any time. Photo is for reference only and shows only a partial kit. Electrical and vacuum lines must be run from your center console/dashboard to the exhaust valve. Professional installation is recommended.
