DirtWheels did a pipe shootout and the white brothers won. Another magazine (I think it was atv connection) did the same shootout and the curtis sparks pipe beat the white brothers. (DirtWheels didnt include the curtis sparls in their shootout) So if it was my money, I would get the sparks pipe.

Big Gun is what alot of guys here in my local area of Michigan are using this season. Another strong contender would have to be the Yoshimura exhaust system. The complaint alot of the guys who went with other pipes had with the Yoshimura is its construction, I guess it's pretty crappy according to some. Its power is right up there with White Brothers and Big Gun as for the charts say though.

I've got the Yoshi "race" slip-on, and it is a very well made pipe. I've had FMF, White Bros., and Supertrapp in the past, and the construction of this pipe is top-notch IMHO. I've drag raced guys with the E-Series pipe, and it's just about a dead even match, but I always seem to pull away once we hit 5th gear. That probably has something to do with jetting though. Anyway... I say get whatever pipe you can afford...they all give about the same performance. I personally didn't want one with a disk spark arrestor, and I've used Yoshi pipes on street bikes for years. That's my $0.02

If you ride alot in populated areas, you may want rethink the aftermarket pipe unless is is designed to give some power increase without being a lot louder. Almost all of the aftermarket pipes are ALOT louder than stock. This is how people get annoyed with quads and dirtbikes and close down our riding areas. Do what you want, but I would think about your neighbors and the future of our sport.

I have owned a White Bros E-series and a yosh pipe and neither of them stack up even close to the performance, look and sound of my LRD pipe. The LRD one even looks so much better. New pipe this year. The LRD one may be a little more expensive but if you plan on moding your motor go with a quality full system.
