The FMF Gnarly pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. Super strong 18 gauge steel construction makes it GNARLY! Nickel plating is an FMF trademark and has been ‘copied’ by everyone making it the most imitated expansion chamber in the world.
Maybe I'm biased maybe I'm a fanboy maybe I just like there tshirts what ever the reason I've always used FMF and have never had a reason to leave. This replaced a pro circuit system the bike came with.
