I'm thinking of getting MAC longtubes, MAC shortty o/r prochamber, and borla stingers. Do i need to purchase any extra hardware for a shop to do the install? My mustang is a 2003 gt with about 73000 miles on it. I dont care about the MILs or O2 extensions because i will soon also get a SCT tuner and i should be able to turn that stuff off correct? I'm more worried about gaskets and things like that. I just want everything in the install to be smooth and how much do you think labor will be? yes i know that it might be expensive because of the longtubes.
