FMF KTM 250SX / EXC Husqvarna TC250 19-22 Factory Full Exhaust System

FMF RACING FACTORY FATTY EXHAUST SYSTEM

FMF Racing is a company that specializes in the production of high-performance motorcycle exhaust systems. One of their most popular products is the Factory Fatty Expansion Chamber, which is designed for off-road motorcycles. The expansion chamber is hand-made from high-quality materials and is engineered to increase horsepower and torque, while also reducing weight. The design of the chamber allows for improved exhaust flow and a more aggressive exhaust note. The Factory Fatty Expansion Chamber is a popular choice among off-road Motocross riders looking to improve the sound and performance of their dirt bike.

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.
