So I followed the method of putting the car in Sport/Dynamic and then turning the car off. I unplugged the exhaust valves and then went for a drive. I feel like there is absolutely no difference in sound at all.. to the point where I think I may have even closed the valves rather than permanently kept them open?
I parked the car and put it in economy, then went out to the pipes and there is hot air coming from all 4 pipes that's for sure. Does that mean I've successfully opened them?
Also when I drop the car into Sport from standard Drive, I can hear the noise of the exhaust change as if the valves have just opened however surely thats impossible as the cable's are disconnected?!
