This is a quick video clip of some revving in my M2. It’s a 2017 with M DCT. I also have the M Performance exhaust. The valves are closed in this video. I repeated the clip four times within this video so you don’t have to keep hitting play to hear it a few times.
This was taken on a chilly 30 degree F morning in my work parking garage with my driver window cracked.
