Hey guy, I had GT takeoffs on my other V6 and my uncle was the one that worked on the car putting the dual exhaust on. He is over seas and can't really help right now with my question. I am thinking of getting the american thunder or the borla stingers dual exhaust. I understand that the pipe is smaller for our V6 compared to the GT and the shop I took it to didn't want to do it if I had the mufflers sent to them. With that happening I was kind of mad that it might not work but I know I have seen people on here with those mufflers on the V6. What all do I need to get to have it installed on my car safe without causing problems if I actually can find a shop to do it since I don't have the tools to do it myself.
