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.

All the midpipes fit the same whether its a GT or Cobra so thats no problem other than the standard Mac fitment issues, and the extensions depend on if you have an 03 or 04, i believe you need them for the rear of the 04s but its been awhile since I did this stuff so dont quote me on that part lol

The rear O2's on the 04's are further forward. So if you want to keep them you'll need extensions. If they're turned off you can plug them. The fronts look like you'll be fine on that one. I ran O2's with longer pigtails on my Bassani as the bungs were on the bottom of the pipe and stretched the harness a little more than I liked.
