For those of you who are leaving the valves open by pulling the connectors next to the external valve actuators, make sure you wrap/tape the connectors up very well as they are electrical connectors and you don't want them dangling open to the elements. Also, obviously, you would need to make sure valves are in the open position before you pull the plug. I think they stay open when you shut the car off in sport or sport+. Shine a flashlight into the tailpipe and you can see if the valve is open or closed. Pull plug only when exhaust is open or you will have a nice, quiet permanent exhaust note.
