Has anyone seen a x/h-pipe comparison test?

[96GTBYYOU]

My local race shop (B&D Racing)claims that the X is good for about a tenth of a second over the H in the 1\4. They tried it on a 5.0 though, not a 4.6 - for what it's worth, I have an X from Bassani & love it - I suggest 3 chamber Flow Masters - I have 2 chambers and my fillings are getting loose! Sounds great though - I can't even hear those annoying ricers that are buzzing around town (behind Mustangs!) Good Luck!!
