Several months ago I replaced the center and rear mufflers on my 92 300E w124. I bought OEM units from a website out of Dallas. The mufflers were shipped from CA. I bought the rubber hangers and metallic type gaskets from the same source. I toke my car to a local Meinike shop for installation. They welded the unit on because I didn't want to take the chance of a leak. My total $$ for mufflers and installation was $387.xx. My advice is buy new hangers and metal gasket where the middle and rear connect. The pipes on the rear muffler turn down because this an OEM muffler.
