Do you guys have an suggestions on a shop to use for welding in a muffler? I am thinking about getting a flomaster 50 or maybe Borla exhaust but dont want to pay for a cat back. I am looking for a louder throatier sound but not ricey. I have an 05 4.0. I am in the Worcester MA area but was wonder if any national chains are ok to have to this. Should I buy the muffler or have the shop sell me one? I would do it myself but I want it welded and dont have a welder.
