With these electronic exhaust flaps (for subsequent installation) you can control the volume of your exhaust system using a radio remote control. When the flap is closed, there is a subtle exhaust sound. As soon as the flap controls are activated (remote control), the flaps open immediately and the exhaust system sound immediately becomes significantly louder and sportier. You can either return used batteries that we carry or have carried in our range as new batteries to us at your own expense or return them to our shipping warehouse (shipping address) free of charge. Alternatively, you can hand in the batteries at the local collection points. Old batteries can contain pollutants that can damage the environment or health if not properly stored or disposal. Batteries also contain important.
