SLP pipes for the Yamaha Banshee. These are probably the best pipes we have ever tested for MAX H.P. and torque. If your looking for great low and midrange power then these pipes are the answer. They work especially well on our big bore cylinders both the 392cc kit and the 421 kits. They are a lower RPM pipe compared to most with a similiar power curve to that of an FMF fatty but with a much higher peak H.P. number. These pipes were tested on our 392cc cylinder kit with stock carbs,v-force reeds and pump gas domes and the bike made 72H.P. and 44 ft lbs of torque. When we tested them on our 421cc Low port kit with v-force reeds, pump gas, and 35pwk's they made 84H.P. and 50+ ft lbs of torque. Pipes include silencers and silencer mounting hardware and come with a Nickel plated finish.
