Just picked up a 2008 Road King Classic. For the last 6 years have owned Yamaha V Star and Roadstar. The Harley is a whole new experience. I'm no junior, turned 63 last week, and had to have a Harley. Please excuse me if I ask some dumb questions. One question I do have is about slip on exhausts. The pipes on my bike are stock and too quiet. I want to add some noise but not too much. What would you recommend, and will I have to do anything other than just add slip ons? Thanks in advance.
