My buddy has an 04 GT and want's to buy an x-pipe for it. The local speed shop has told him that he can't get one from them, because the mid-pipes for 99-03's won't fit on his 04. Yet every catolog I have looked at says it is for 99-04. What does he need to do make an o/r x-pipe work on an 04. I 've looked at it and the only diffrence I see is the o2 sensor plugs up in a diffrent spot. Need him to find one soon so he will quit asking me for mine!
