I trying to find out what the best pipe and header set up is the best for a 2000 yamaha warrior. I've been leaning towards either a big gun or white bros.

 

Header does nothing for it but look shiny. Best pipes are HMF and White Bros if you want power.

 

buy a blaster and put a pipe on it!

 

did the research last year...majority of the responses i got stated the WB e-series...so i bought it. bought the header pipe as well... a tourqe stuffer (which i don't think added mch of anything) proflo air filter, motoforce airbox cover (clear lid cover to view filter with two huge intake vents) and a dial-a-jet ( i ride mountain trails, summer, winter). could'nt be happier. between adjusting the dial-a-jet and finding the right combo with the tunable discs on the e-series...it took a couple of months to dial it in. Oh yeah it also became very loud...so i added the q-core ( minimull loss)
