FMF Factory Fatty Pipe for the Fantic 2025+ XE300

The FMF Factory Fatty is an expansion chamber designed to provide performance gains across the entire powerband. Built with a focus on a "factory" aesthetic and increased power delivery, this pipe utilizes lightweight materials and hand-pounded seams to emulate the performance characteristics of works-level racing components. The Factory Fatty is a direct replacement for the OEM pipe, offering improved throttle response and increased over-rev.

Performance:

• Broad Power Gains: Engineered to increase horsepower and torque throughout the low, mid, and high RPM ranges.

• Material Construction: Constructed from lighter 20-gauge steel for the body and 19-gauge steel for the header portion for optimal weight savings and resonance.

• Hand-Finished Seams: Features hand-pounded seams for smooth internal transitions and improved exhaust gas flow.

• Raw Finish: Supplied with a non-plated, "raw" finish that provides a factory racing appearance and requires proper maintenance to prevent oxidation.

Features:

• Fantic XE300 Fitment: Specifically tuned to complement the power characteristics of the 2025 300cc Minarelli engine utilized in the XE300 platform.

• Direct Bolt-On: Designed to interface with the factory mounting points and the original FMF-sourced Fantic silencer or aftermarket FMF silencers.

• Weight Reduction: Offers a significant reduction in weight compared to the standard heavy-gauge stock expansion chamber.

• Quality Control: Manually checked and finished to ensure precise fitment and performance consistency.
