All these guys are correct. I started out with the Yosh RS3 Race slip-ons, but later decided on a full Micron system. I love my Micron. BTW, I've been trying to sell a set of Yosh RS3 Race stainless slip-ons for the last few months. They have less than 400 miles on them and are in pristine condition. The only blimish is a couple small dents on the underside of the right can, and they are not noticeable unless you run your hand under there. Got a deal on them too. I'll let them go for $430 and I'll pay shipping in the U.S. only.
