i got a YFZ for xmas and want to give it more power! exhaust is the way to go, (i think) but i dont know which one to get? my main 2 are Sparks and HMF. (you can name some other ones too) give me some info about power gains, noise, and how you liked the ride. thanks yall. :rock

HMF is a very good choice ,i do not know about sparks,if you like a price PM me back,i can also send close jetting for your area.www.willmansoffroad.biz,or call for a price,the price on the internet may not be correct,due to restrictions on advertising low prices.NOISE it's a little loud ,the other riderswill move. thanks hope to talk soon MARK
