Save $25 when you combine the new Power Intake Tube with the aluminumGrunt Exhaust Manifold Exhaust manifold. Together they are a huge improvement in pulling power, from just right off of idle all the way to wide open. Requires either using the TPS Tuner to increase Fuel, if you won't be going past 3/4 throttle much, or using or proammer or the Vortex ignition we have, to get enough Fuel to the bike, from 3/4 to full throttle. The big bottom Kit is a big power increase, after opening the exhaust and increasing Fuel.
