FMF Racing Factory Fatty Pipes

Not Yet Reviewed

FMF Racing Factory Fatty pipes are a close reincarnation of the "works" pipe used years ago by factory teams, sharing many of the same characteristics, with their craftsmanship and material quality. Designed to broaden and smooth out your entire power band, they give them the benefits you're looking for, no matter what type of riding you do. They feature lighter 20-gauge steel on the body, 19-gauge steel on the header portion, and have hand-pounded seams for smooth flow transition. If you're looking for a great pipe that offers better all-around power, FMF Racing Factory Fatty pipes are the ones for you.
