Hey guys I just purchased a brand new 2006 YFZ450 and along with it I got an HMF Full system with CFM Performance airbox/K&N. I was wondering if anyone has this combo on here or what increases any of you HMF on YFZ owners had.

 

The HMF is a good system. It seems to be more of a low/mid mx style pipe, but the top end certainly doesn't suffer any either. You will be satisfied with it unless you are going to strictly drag race the bike.

 

Have one and love it.

Although I truly believe that there are probably six other pipes out there that are just as good. If you don't believe me, just wait and see what some of the replies are to this thread. LOL

buck183, that is so true, lol. Tons of good systems out there, but I like HMF's support and the fact they will fix/repair your exhaust, usually for a reasonable price. They have a good webby and forum too, which swung the decision in their favor for me.
