Hey guys kinda new hear but i have a few questions. First, how much would you expect for just labor to change my V6 2007 Mustang's single exhaust to a dual exhaust and it would most likely be a catback setup. I dont know really know a lot about what im talking about to any tips or info would also be great. Also i would probably go for Borla i love the sound and the place i would get it at offers them all at around the same price? idk if thats weird also seemed like borla should be more expensive then some other brands but w/e im not arguing. Once again single to dual and info thanks a lot!
