WOW, according to daddog's instructions that'll get ya YFZ guys about 6-7 hp gain.
I'll tell ya 1st hand being a new rider to quads and only haveing about 15 hours on the YFZ and then doing that, i noticed a very big difference. Idles better and the powerband is really smooth all the way through. Man she ripps now. I'm still waiting for the GYT-R pipe to come in...now i think i'm going to cancel the order and buy myself a new set of boot's instead!!!!! (that's enough power for me right now)
