I heard a set of these mufflers (model # 80491-07 /slash down) and thought this would be the ticket to a quieter pipe with a little rumble for my 97 Road King; problem is, they only fit 07 & 08 models and Harley isn't offering them for 09 as of yet. I'm wondering who makes them for Harley and if they can make them to fit prior 07 carbureted touring models?
