Description
The FMF Factory Fatty Pipe delivers a broader, more responsive power curve across the entire RPM range—exactly what you need whether you’re chasing lap times or tackling varied terrain. By combining lighter-gauge steel construction with hand-pounded seams, this pipe minimizes turbulence while reducing overall weight, giving you measurable gains in low-end torque, mid-range punch, and top-end over-rev. Built to the same exacting standards as factory competition exhausts, the Fatty transforms how your engine breathes.
