Allows you to control the valves regardless of engine settings. Had this on my F80 M3 and now on my F86 X5M.
Works great. Easy DIY install. Can even use the HomeLink buttons on your rearview mirror to control open/closed/factory settings.

Also, for those who have a BM3 tune, you can code this exhaust flap setting to: always on/always off or automatic, regardless of engine settings.
