Well il tell you what i do think the  fmf isn't  much better then the stock pipe.It is a clean pipe, really smooth.But like i said it doesnt have much top in it.Im not big into dyno numbers, anyone can make a page that looks good.With good numbers You know without good proof of the runs of the machine that is on it.Im talking about a page printed at the bottom of a website.With no video proof  just printed.I just wanted to know what people like about the pipe.I will know next week if its good or not.But i do trust the opinion of people  who have runs several different pipes and setups.Eveyone i talk to said they like it and was worth it. I really havent run to many setups on these quads.I really didnt want to try 20 year old pipes that have the same design when these quads were new.Im going to post the difference  in this pipe when i get it on and jetted correctly. I think will work out great and i will like it.Just cant wait till  i get and try it.
