Hello all. I have a 2000 100 series that I need a new muffler on. The rest of the exhaust system looks decent but the muffler has a considerable hole in it. I have taken it to two mechanics in the Albany area of NY. The first said that it was impossible to replace only the muffler and I would need to replace almost everything south of the cats. He quoted me 1k for a walker system and 2k for something a little nicer. I took it to another mechanic who was willing to remove just the muffler and quoted me $680 for install of a new walker aluminized steel muffler. I found posts from a few years ago quoting installs for quite a bit less than this but I am also aware that things have gotten much more expensive the past 3-4 years. Does these seem reasonable to you all or should I keep looking?
