the best pipe for my R

[honda-man88]

I have a Paul Turner ATC type 2 Fat Boy pipe and i was wondering if there was any better pipes out there that could improve preformance a bit. The reason i'm asking is because this one is getting old and i've re-packed it twice now.

From my experince, those and ESR pipes are about the same, and I like their powercurves the best.
