FMF - FACTORY Fatty Pipe
The Factory Fatty has the same shaped cone sections as the popular Fatty
pipe, but offers some new features. The Factory Fatty is constructed with two
different thicknesses of US steel. FMF uses 19 gauge steel for the header
portion for optimum strength and durability, and uses thinner 20 gauge steel for
the body and rear cone section for increased weight savings. The thinner steel
also yields a slight increase in power when compared to thicker materials (up
to1/2 hp) due to more efficient wave resonance. During construction the seams
are all hand pounded after the stamping process to give it a smoother transition
between sections and that factory look. Last but not least, this pipe does not
have the Gold Series nickel or chrome finish that FMF has been synonymous for.
This pipe comes with a raw, un-plated, oiled finish. The Factory Fatty has a
tremendous amount of attention to detail.
Bolting on a Factory Fatty pipe will enhance the powerband throughout the range.
With increased horsepower and torque, you will not be sacrificing power to gain
that full factory look. All of FMF's pipes go through an extensive R&D process
with dyno and track testing with a full gamut of test riders with various skill
levels, to make sure what is released to the public has Don's seal of approval.

this is a really good pipe, i use this with a shorty.... It doesn't give the bike alot more "power", allthough it is a smoother powerband and it pulls alot longer than stock. the stock pipe definatly had more power on top but it didn't rev very far... This pipe brings the power down to the lower rpm:s. It's still very strong and fast in the higher rmp range but not as strong......
This is a very good choice for 2-strokers out there who want's a stronger bottom-mid and a longer pulling top.... And bto had an awesome service ofcourse!
