Searched enough for one day...please comment..

go gnarly. better bottom end and mor dent resistant.

Just FYI - i and others have found FMF products claim to fit a certain model but just dont quite work. I got a PC silencer and it didnt quite fit perfectly so i ended up spending more time than what i wanted to. I definately am not going to purchase new FMF products for this reason. For the price, FMF should care a bit more.

U could search and see other peoples comments about FMF

And if you still want to get a FMF pipe - watch E*bay carefully

Id go with the fatty more power everywhere. :nener: :nod: :laugh:

I liked the fmf gnarly pipe only becuase it tends to hold up better when you drop the bike. If you bought the bike used double check the timing a lot of people retard the ignition on those bikes to gain top end and use pump gas , if need be go back to stock timing you will need good quality fuel though. If you use pump gas think about running a race fuel and you can jet a lot cleaner/crisper with out fear of detonation from the stock head set up.

The fmf pipes fit ok but you have to remove one of the powervalve cover bolts to get the pipe in between to frame rails for the exhaust port and then when the pipe is loosely flopped in there you can put the bolt back in. atleast mine was that way

The FMF stuff fits really poor on the oldey YZ. I cannot comment on the 94 exactly, but the 97 and 98 pipes are very poor fitting.

After I complained, some of the people who had been here longer told me FMF stands for "Fit-MOTHER@@@@@@-Fit!"
