I just bought a 02 v-star 1100 for my second bike and want to put on a set of slip-ons. This is the first time changing exhaust on one of my bikes so I have a few questions. First any suggestions on a set of slip-ons? I am looking at the Roadhouse Brand Moto Classic Slip-on Muffler they are a 3.5" dia. slash cut. Second do you have to rejet with slip-ons? I have heard people say you do and don't. Thanks for the help.
