I have a 2006 Harley Road King and it has stock duals. I want to keep the look of the duals but I want it to be louder. I don't want to wake the neighborhood but I want people to hear me when I'm on the throttle. What kind of pipes or slip-ons would fix both of these? I haven't ever changed pipes before is it something that I can do pretty easy or should i just shell out the money and pay the harley shop to do it?
