best exhaust

[edj3663]

Im lookin at gettin a banshee for my next bike, I dont know a whole lot about 2 strokes but I know stock is a bad word. Ive heard good stuff about rocket pipes, shearers, toomeys, and cpis. Now what do you guys think is the best? I already have a trail bike so it will be for everything except that, I think a powerful topend would be better for dunes, motorcross etc. Please share opinions.
