i run these on my banshee for tt and i found that they give major power gains on the mid to top end power i love these pipes not to mention great sound
i have a 01 banshee set up for tt and i have a vito's boost bottle, bored .80 over noleen pipes, reed spacers and 2 k&n's right of the carbs and the throttle response is like my dad's cannondale witch is fuel injected.
