With just a slip-on. http://www.muzzys.com/ZX10/ZX10-Stock-v-Slip-on.gif

thats a powerful stock engine muzzy got there. You sure thats just a slip-on?

According to Muzzy, it is a slip on with a PC III. BUT, Muzzy hisself has said those numbers seem almost to good to be true. He is going to retest with another bike to verify the gains. Gee, what a refreshing approach from a manufacturer. Shows a lot of integrity.

I'd done business with Muzzys for three years now. They've been a great company to work with! All top notch folks. :)
