my 95 E300 is mostly stainless. I replaced the rear muffler last fall and it was rusted on all the seams. Themiddle muffler and pipes are stainless and look brand new. The front pipes and cat. yes cat are stainless and are cracked at the seams. Welding has held off the gremlins. However the list on the front pipe and cat is $1570.00 and only available from MB. Now theres a worry and a half
