Just got my tuner and am getting the car inspected this week, so after that the Mac H can go on. I did some searching but am having a hard time finding answers. From what I gather this GT version will fit but I may need 02 sensor extensions...I've also seen comments about needing some fab work done on the end(s) that connect to the factory headers? I was going to try this in my garage but if modifications are required I'd think my local exhaust shop would be better suited.
