Why replace a center pipe with an x-pipe?
Sounds like the ideal exhaust upgrade (especially on an L98) would be to convert to headers and duals WITH AN X-PIPE!
Can't argue with headers. Can't complain about duals. But....
If the original setup had a "Y"-pipe that merges the two sides -- only to split it again, why not leave the center section as one pipe? Why even convert to duals?
I can see increasing the center pipe to 3.5" or 4" center pipe -- as you increase the size of each "feed". Just curious why an x-pipe or h-pipe is considered more desirable? Is it an image thing? I have to admit I like the idea of an x-pipe over a single, merged center-pipe. But I also have to theorize there's probably no functional difference!
P.S. This question has nothing to due with increasing the stock exhaust diameter. I concede that point as well!

The difference will be in sound and some slight low-end improvement.
Adding crossovers is like lengthening the collector of a header primary, it can slightly improve your low end. The sound benefit is that it kills some resonance at low rpm.

Are you saying that an Xpipe or Hpipe does a better job of adding to the low end and/or dampening resonance vs. routing thru a common center pipe (as in the stock L98 config)?
-- or --
Are you explaining why true duals are joined these days? (whether it be an Xpipe/Hpipe/Ypipe).
