I know this has probably been covered a bunch at this wonderful site, but can anyone give me some helop on slip-ons? Been wanting to change the sound from stock mufflers to something with some loudness. when ordering the Rush slip-ons they have baffles sizes that you can order. What is one that would sound good on a 2003 Road King? Is it the smaller the baffle the louder it gets. The bike is carbuerated and I am aware that it may have to be re jetted. Just wanting to get some ideas what would be best.
