Fatt Azz Pipe / F7 Big Bore Category_Default Category/SLED/Ski-Doo/1000 SDI and a primary springOur BMP Fatt Azz single pipe is one strong single pipe! The neat part about this pipe is it likes to be worked hard and it has an amazingly wide powerband. This is the pipe we use to make our F8 big bores make 170 174 HP and over 180 HP with our F9 big bores. The powerband at wide open throttle is from 7700 8200 RPM. This is crazy wide power that is easy to clutch and make haul Azz! This pipe is designed to only work with a BMP high flow manifold and
