Check out these bag boys!! I ordered them at the same time as a set of Akrapovic’s (without the slip-ons) but as they arrived first I couldn’t wait so fitted them to the standard down pipes..and BOY does it sound GOOOOD!! About as loud as the ‘Jim Mod’, maybe a little loader but without that deep resonating echo. I did order the baffles to go with it but they are on back order. As they are designed to run with or without them it gives me the choice, depending how annoying I want to be.
