Will my exhaust system from 91 gt bolt up to 82 gt?
 

I am the one that just bought the lady a really nice 82 gt. My question is I am going to be putting an aftermarket off road h pipe on my 91 gt and i am going to put the flowmaster kit on to! I was wondering if i could get away with using my exhaust off mine on hers becouse hers is only single exhaust?? Probably not just being selfish to save more money for my mods lol!

You'll need a double hump crossmember for your 82GT, and different headers if I'm correct. Otherwise with new hangers it should bolt up.
