I just got another banshee yesterday, pretty much stock(for now) except a 2into1 pipe and lonestar axle, The shee is pretty beat up and has been raced, anyways it has a fresh top end, starts up first kick, but with the 2into1 pipe it sounds AWESOME, however it does not perform well, my brothers stock banshee can take it in a drag, it feels like there is no bottom end at all, only once you get in the power band will it go. But for being piped it is not that fast. It also seems like it is jetted right, no bogs or sputters. So, i do not think this pipe is that good for performance.
