i've got a slight problem getting hold of a exhaust for a w202 c180 1998 my current exhaust is a 1 piece system, i've contacted several exhaust centres plus a local mercedes specialist who tell me my exhaust is no longer available, the earlier 202 aftermarket exhaust is a 2 piece system according to euro cars parts this is what i should fit as the 1 piece ones are few and far between now is this correct? cheers for the replys in advance
