I've acquired a full M3 exhaust system via QM - Great service / price from these guys by the way.
Before I go about fitting it, has anyone done this and what problems have you encountered. I'm totally comfortable with what has to be done, but did you have to replace anything when hanging the center section? Does the backbox hang OK on the OE non-M brackets?
I'll be replacing the o2 sensors, exhaust manifold nuts and gaskets etc as I go.
