FMF Racing Factory Fatty Exhaust 025243 for Dirt Bikes

The Factory Fatty exhaust expands the power curve from idle to over-rev, delivering more low-end torque and stronger midrange across the dirt-bike power band.

Reminiscent of the classic Works cone pipe, this design combines precise craftsmanship with durable materials to optimize performance. It uses a lighter 20-gauge steel body and a 19-gauge header, with hand-pounded seams that ensure smooth flow transitions. O-rings are included on most models to simplify installation and maintain a reliable seal.

Engineered to optimize exhaust flow, the Factory Fatty delivers improved throttle response and increased horsepower across a wide RPM range. Riders experience more immediate power delivery, better controllability in technical terrain, and extended over-rev performance when you need it.

Built for durability and easier handling, the lightweight construction reduces rider fatigue without compromising robustness in tough riding conditions. The system is designed for easy installation and compatibility across multiple motorcycle models, making it a practical upgrade for off-road and motocross setups.

• Enhanced performance with improved throttle response and power across the RPM range
• Lightweight construction with a 20-gauge body and 19-gauge header
• Hand-pounded seams for smooth flow transitions
• O-rings included on most models
• Easy installation with broad compatibility across multiple dirt bike models

The Factory Fatty is reminiscent of the “works” or cone pipe once used by Factory Teams. It shares many of the same characteristics with its’ craftsmanship and material quality. The Factory Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you’re looking for.

• Lighter 20 gauge steel used for the body of the pipe.
• 19 Gauge steel used for the header portion.
• Includes O-rings on most models
• Hand pounded seams for smooth flow transitions.
• O-Rings Included
