Which valve for louder exhaust?
Has anyone managed to figure out which valves in the exhaust can be permanently left open to make the exhaust sound better?
I did this on my M2, just unplugged one of the valves when it was open and it made a difference to the overall exhaust noise. Is this possible on the Z4 M40i? Thanks
