Heres what I know, yoshimura is one of the baddest pipes,it's truly a quality piece and comes in 3 different styles, performance wise whitebros is a tick better than the fmf but costs more and most dont come with the head pipe!!!, I personally like the big gun becuase my wolverine is dead i have the fmf and megamII both are good the megamax can be mad as quiet as stock though with queit insert and discs its extremely queit but has more thump!, all the pipes are a fairly substantial improvement over stock, and with a unifilter(especially if you ride in sand) and rejetting and you'll have a free breathing machine!!
