I was given the part number for the rear section exhaust for my car by a Mercedes dealer near me, number A204-490-36-35. cant get a new one but looking on ebay for used ones their are a few BUT with the part number A204-491-16-01 and for diesels. the sellers say they also use the part number for my car quoting both numbers in their listings, looking at both exhausts they look identical, can anyone confirm this before i buy one ? cheers.
