Hey purchased my first bmw, 2008 e91 320i joined up to check info out when a problem occurs, at the moment car has done 120xxxkms and looks like the cats are stuffed, so was wondering what people do, change them out or get some straight pipes with the o2 sensors stuck in... interesting to know.
My old man just purchased a brand new m3 sedan also, bloody nice machine.
thanks all
Adam
