Yamaha YZ250 1984 - 1986 FMF Fatty Exhaust Pipe Expansion Chamber Nickel 020124

FMF Fatty Exhaust Pipe Expansion Chamber Nickel

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
