So sick! Pit bike must have!!!!

Everything you'd expect from FMF in a smaller package. A huge performance boost only 4 bolts away. Way sick!

fmf fatty gold series pipe

this pipe sounds really nice it seems more throaty and has a lillte more snap but that may be wishful thinking. overall i like the pipe but is was awfully tight for installation and seems to stick out a long ways and if tipped over since it has rubber mounts may dent it with the bolts on the engine if it got pushed in but with the powercore II silincer it sounds great.

Fit right on no hassles.Comes with O rings and jetting recomendations.Nice plated finish easy to clean.Added a little pep to engine, but still very controlled for tight woods.Im happy with the performance.

Great Purchase

The FMF Fatty made all the difference, all the way up through the power band. Just don't let it get to beat up. You will be able to tell the differece if you do.
