The FMF Factory Fatty Pipe is a 2 stroke exhaust header that takes cues from the works pipes of yesteryear, smoothing out power in a lightweight construction that pays tribute to the racers of old.
With the Fatty Pipe expect a smooth power band devoid of spikes but with better power throughout the rev range. More low, more mid, and increased over-rev. Great for most types of riding where you want more control of your power band.
A bare finish that shows the heat-affected weld areas is attractive and true old school. The construction is also full of old school quality with lightweight 20 gauge steel for the body and thicker 19 gauge for the header portion. And of course it has the same hand welded, hand pounded seams to increase flow.
