For my birthday, I bought an off road h-pipe from a local enthusiast. Couldn't pass it up because $60 was a great price. He said that it was on his '04 GT and should fit mine without issues. Well, I've heard that before and before I start tearing into my '98, are there going to be any surprises I should prepare for like flange size differences, hanger location, etc? I know from my pushrod experiences a foxbody midpipe fits a 94/95 but there are minor differences that make it a complete pita at times.
