i'got a 2003 yamaha big bear and i am wondering which slip on is best for it. the two pipes i have found are the white bros. e series ($215) or the supertrapp ($210) @ rockymountainatv. also if i get one of these would i have to re-jet and change the filters? also if there r any other slip-ons for my bb can you please inform me about them.

 

HMF and FMF both make slipons for the bigbear...i know the HMF says you dont have to re-jet...but if you want the most power you can get you have to rejet anyway

 

do you guys also have any info on the fmf megamax. it doesnt have to be for a big bear just reply if you wanna tell m how they perform. info on the hmf would be nice too.
