FMF Factory Fatty Pipe 025183 — KTM Husqvarna 125 150 2016-2019

Product Description

The FMF Factory Fatty Pipe is inspired by the legendary "works" cone pipes once reserved for professional factory race teams. This exhaust brings that same professional-grade craftsmanship and material quality to your KTM or Husqvarna, effectively broadening and smoothing out your power curve. By providing substantial gains across the entire RPM range—including stronger low-end, improved mid-range, and increased over-rev—the Fatty is the premier choice for riders seeking versatile performance in any riding environment.

Engineered for both performance and durability, this pipe uses lightweight 20-gauge steel for the main body to reduce mass, while the header section is reinforced with 19-gauge steel to better withstand the rigors of off-road racing. The precision hand-pounded seams ensure smooth, unrestricted exhaust flow, eliminating turbulence to maximize your engine's power output.

Frequently Asked Questions

Q: Does the Factory Fatty require any specific silencer?
A: The Factory Fatty is designed to work seamlessly with both the stock silencer and FMF performance silencers to suit your power delivery preferences.

Q: Is this pipe more durable than stock?
A: Yes, with 19-gauge steel at the header and high-quality construction, it is built to handle the rigors of competitive motocross and off-road riding better than standard stock units.

Expert Pro-Tip: Always check your jetting when swapping to an aftermarket pipe. Two-stroke engines are sensitive to changes in exhaust scavenging; upgrading to a higher-flow pipe often requires a slightly richer main jet or needle adjustment to maintain peak engine longevity.
