Purchased my new Road King this past March, just had my 10,000 mile service this past Monday. My question is: as my stock exhaust system has aged, it sounds different, better in fact. Which has got me wondering.......how long can you expect an exhaust system to last before it needs to be replaced? I'm not a mechanic, don't want to be, and I'm sure there are many miles left on it. Questions just seem to pop into my head about things I'd like to ask about. Thanks for your time.
