RE: QUESTION ABOUT X PIPES
i think all x-pipes will have that raspy, x-pipe sound. you can camouflage it w/ resonators, diff muffler setups, but theres no getting away from the xpipe sound. i really believe the x-pipe sounds better w/ a straight thru muffler. i love my xpipe, love how it sounds, but i know a lot of people dont, its a personal preference. my boomtubes help to keep the sound low and rumbling, but once the rpm's go above 3500, the xpipe starts screaming, in a good way.

RE: QUESTION ABOUT X PIPES
I don't think all X pipes are created equal.
I have a Pypes O/R X pipe and despite its cheap price has good welds at the cross over an the connection is large with a relatively oval opening seen from the inside. I have heard some X pipes might not have as large a connection thus impeeding cross flow which would affect sound.

RE: QUESTION ABOUT X PIPES
A "X" shares the actual flows from the right and left cylinder banks between both mufflers. That generally takes out a lot of the low frequency "rumble" that is traditionally associated with true duals and (to a slightly lesser extent) "H" crossovers. An "H" damps out the peak pressures from each bank a little, but isn't particularly good when it comes to actually sharing/equalizing the flows.
I'd characterize the "X" sound as being more of a snarl once you pick the revs up a bit- smoother and more even, with a higher pitch - and sounding closer to what some folks have done in circle track and road-racing* than what you'll hear at the drag strip if that helps any.
* including Formula 1, if you remember the time when those engines were only turning 9000 rpm or so

RE: QUESTION ABOUT X PIPES
who makes a good quality stainless x-pipe that wouldn't require cutting my old unit in case I want to go back to stock form in the event that I have to go for an emissions test? I currently don't have them where I live but don't know how long it will be this way.
