M235i with m2 exhaust, valves not working
Hello everybody this is my first post on these forums so I'm sorry if this is in the wrong place but I put the m2 muffler on my m235i x drive yesterday and the valves no longer seem to open and close
With the car warmed up fumes only come out of the left side in all driving modes and when u change from comfort to sport I no longer hear the clicking you associate with the valves opening and closing
I would like the valves to work like they normally do left side open in comfort both open in sport and sport plus etc etc and I know others that have not had this problem who's valves worked like normal after installing the muffler, any help would be greatly appreciated!
