I just bolted on my HMF full system on my yfz and all I can say is wow!!!!! I have never felt this much of an increse in power from just a pipe before. tons of low to mid power, and even a little more up top to boot. I have ran 6 different exhuast on my ex and none had this kinda gain. (the hmf on the ex was close though)

Sounds like hmf. I had a slip on on the 400 and it gave alot of power gains, atleat I thought it did. So how do you like the 450 ?

The first day I brought it home and rode it I thought I had just thrown away 6K on a POS. I was Pissed. with a few more rides the and some jetting it seemed to have a little more bottom end and I liked that. now with pipe, correct jetting, shocks adjusted great, and Razr tires I love it. I have a pro level 463ex I have been racing this year, untill to day it was my favorite quad I had ever been on. I think this pipe just put the 450 on top. and to think I have more things on the way!!!!!!
