FMF Fatty Pipe 025241 — KTM Husqvarna GasGas 250 300 2019-2023

Product Description

The FMF Fatty Pipe represents over 35 years of dedicated racing development, serving as the gold standard for two-stroke performance. Designed to provide a broader, smoother powerband, the Fatty delivers significant performance gains throughout the entire RPM range. Riders will experience increased low-end torque, a stronger mid-range pull, and improved over-rev, resulting in a more tractable and controllable machine regardless of the terrain.

Built for the rigors of competitive off-road riding, this pipe is constructed from high-quality carbon steel and finished with a durable nickel plating that resists wear and corrosion. FMF’s proprietary Tru-Flo stamping process guarantees a perfect fitment and consistent performance, ensuring that your bike performs exactly as intended every time you hit the track or the trail.

Frequently Asked Questions

Q: Is the nickel plating just for looks?
A: Not at all. The nickel finish is specifically applied to enhance durability, providing a rust-resistant layer that helps the pipe stand up to the elements and cleaning chemicals better than raw steel.

Q: Will I need to adjust my fuel injection mapping?
A: For TPI models, the ECU generally compensates for exhaust changes, but for optimal performance and engine longevity, a performance map or tuner is always a great addition when upgrading the exhaust.

Expert Pro-Tip: When installing a new pipe on a TPI or EFI two-stroke, ensure the exhaust flange O-rings are seated perfectly. These bikes are highly sensitive to even minor air leaks at the flange, which can cause erratic idling or inconsistent power delivery.
