These ZEX Hayabusa dry nitrous systems are the only kits of their kind on the market today. Easy to install in only a few hours, these kits come with everything that you need, including a custom bracket that hides the nitrous bottle under the '99-'07 Hayabusa's "hump." These kits include a patented electronic TPS switch that activates the nitrous only at wide-open throttle and gives you much better control of the nitrous "hit," compared to the more common horn button activation.
