FMF Factory Fatty Front Pipe Exhaust

Description

• The Factory Fatty is reminiscent of the “works” or cone pipe once used by Factory Teams and it shares many of the same characteristics with its craftsmanship and material quality
• Broadens and smooths 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
• Hand pounded seams for smooth flow transitions
• NOTE: Will not pass 2025 FIM sound regulation
