you can take that how you want it..the models for a gt and gts are different..but not by much. there are people who have had relatively few problems mounting exhausts on gt models that were meant for gts'..so i think you'll be fine. probably just a little extra work. if you can't do it yourself, then i'm sure any half decent shop can do it for you.
