so im going to start saving up for my slip on exhaust for my 06 600rr.

im torn between the sato and the yoshi...2 different style imo...but they both look so hott.

im looking for a noise make and somewhat of a performance gain....obvioulsy im not going to see much so imlooking for the noise to let cagers know im there...


so how loud is the sato cause i have yet to see anyone with it...

and i know what the yoshi sounds like....


edit:

ive been seeing on a few models you have a "street core" and a "race core"

whats the difference???
