Anyone upgraded their stock M3 E36 exhaust and want to get rid of it? I am looking for a cheap catalytic converter OBDII in Raleigh, NC area, but willing to go to Charlotte, or east to Greenville. Or if someone is looking to buy a 1997 M3 with 140K miles (needs front tires and a catalytic converter to pass inspection), make an offer. Asking $5500 OBO. Would be a perfect car to make into a racer. Won't check this posting frequently, so email me at patidar@email.unc.edu
