Hi,I have a E35 325i with embarrassingly loud original rear exhaust now...Previously, in the old forum, I read about someone who did a good job cutting the exhaust and repacking the material inside. Can some kind soul please repost the directions to the workshop ?Or alternatively, does anyone know where to get a good deal on a E36 325i rear exhaust (new or used) and how much to expect ?shlim'91 E36 325iA (non-cat)
