To X-pipe of H-pipe that is the question!!!!

[ac97gt]

i think this is what Red Mustang Gt 46 was saying, but i put the bassani catted x pipe on my (stock) '97 (it already had flowmasters), and the sound was not all that different. i did notice a slight difference in power (or maybe its in my head) in the upper RPMs though. the sound became more "throaty" but it still sounds like the flows. i was hoping it would get alot louder than it did, not that it doesnt sound ok, but i wanted it even louder than it is now. i sorta wish i went with no cats, especially since ill probably buy a newer stang before mine is up for inspection again (the only reason i bought the cats). i think it is supposed to pass inspection, but bassani offers no garuntee that it will. are you looking for cats or offroad?
