Has anyone with an e92 xi/xdrive done the OEM exhaust mod in the thread below? It seems like a cheaper route to essentially get the Performance Exhaust sound.
Modify OEM exhaust to sound like PE exhaust
I was thinking about trying this. At this point I'm not interested in downpipes due to the cost and smell.
My plan is to cut open the outside portion of each muffler, remove the resonator on the divers side, remove the perforated pipe on the passenger side and replace both with straight pipes. I would then put the packing back in (50% each side.)
EDIT: Found a thread in the N55 subform where Sidewinderpb has done this on his e92:
