I'm looking to get my resonator eliminated and a new muffler installed. Mufflerman in brockton quoted me $168 for the whole job including a flowmaster delta 40 muffler. That seemed a little high to me considering I can get the muffler off of Ebay for around 50 bucks and everyone says the res elimination should only be 20-40 bucks. 80 bucks in labor seems a bit high to install a muffler, do you guys know of any good muffler shops in the SE Ma/Boston area?
