My roommate doesnt have the time to weld in my new muffler so I was thinking of bringing it into a shop (I do not weld). I just want to cut the old muffler out and then weld in the new in the same place (fm 50), not exactly rocket science. Since it is so simple I figure I can trust the typical exhaust places (meineke, midas, monro). How much should I be looking to spend to have that done? Would it be much more expensive to get the cat-back done and have them tuck it up underneath a bit more in the back? Is this the process I should be taking or would you suggest an alternative method?
