The FMF Factory Fatty Exhaust harkens back to the custom “works” cone pipes popular during the golden age of two-strokes. It’s built with the same precision and high-grade materials as those original factory-spec pipes, featuring dual-gauge carbon steel construction. The lower section uses thick 19-gauge steel for strength and durability, while the upper portion utilizes lighter 20-gauge steel for reduced weight. Just like the Gold Series Pipe, the Factory Fatty is engineered to broaden and smooth the power curve, delivering enhanced performance throughout the entire rev range—from stronger low-end to heightened midrange and improved over-rev. For anyone seeking a lightweight exhaust that elevates power delivery across the board, the Factory Fatty is an excellent choice.

AND THANK YOU FOR ALL THE AWESOME SCHWEEEET STICKERS !!!! Y’all rock & stuff
Excellent service and reached out to make sure I got what I needed. Got the lever in under a week here in Kentucky. Actually ordered another for another bike because of service.
I was really hoping for this lever to help my 4 year old on his stacyc and it made a huge difference. Closer to the bars, easier for him to squeeze as he is 4 and all around great lever. Super happy with the purchase.
