Hehe... Because your CBR rice rocket definitely needs to make more noise...

Seriously, that's the primary gain you'll get out of a slip on muffler with no modifications to the fuel injection mapping. In fact, it's actually possible for you to lose a little performance by doing this.

If you installed a full aftermarket exhaust/intake and had the fuel map properly modified to compensate, you might see a few horsepower and pound-feet of torque (four or five?) gain and maybe slightly better throttle response. I can't imagine it will make one iota of difference unless you're taking the bike to the track.
