Re: x pipe
search through some of the exhaust threads and read up on the disputes for yourself, you'll find some pretty interesting points.
however, IIRC i did read a thread quite a while back specifically on this issue and it included dyno numbers comparing pacesetter mid headers vs. longtube setups...and after much bickering it showed there was a very small margin of performance between the two. but supporting mods will always factor in, respectively.
