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.
