DIY wanted: BMW performance exhaust installation
Recently purchased the upgraded BMW Performance Exhaust for my 2009 (N54) 135i and I wanna install it myself.
Been searching the forms and I didn't see a DIY. Found one for the 128i which I think might do that trick but if anyone has some suggestions/advice I'd appreciate it. One of my questions is do I need to remove the diffuser to get at the back hangers. No cutting required. It bolts on at the flange. Thanks for the help.
