What exhaust for motos?

[John34]

Every year there is a parade in my small town of Niles, which is located in the large city of Fremont, Ca. During the parade they have the local HOG chapter ride through. In addition they have several police bikes ride through. The HOG bikes are the typical loud Harley but the Police bikes have a kind of muffled, yet deep sound. What are they using? I want that sound on my Softail.
Thanks

I don't know if all of them are like mine, but I bought a former police EG that has Kerker slip ons. Like you said, pretty quiet, but nice deep rumble.

Um, call the police department, work your way through to the department's mechanic, and ask him? Or, you may be able to ask a motor officer in the department. Many of them are very enthusiastic about their police Harley's and would be happy to tell you.
