My two favorite pipes are toomey t5's and CPI's. The t5's are alittle more rider freindly than the CPI's.

its actually comparing apples and oranges in a sense.the banshee is a rocket but more work to maintain power in tighter areas.(more shifting and reving) whereas the raptor has mega torque and doesnt require hardly any shifting.people can dune almost a whole ride in second gear.the banshee eats up gas and have to premix.there is something special about the powerband of a banshee and how they come alive with motor mods.i guess it comes to what you want to do with your bike to choose whats best.they both have strong and weak points.
