So, I was looking into American Custom Exhaust. The company that Takes the stock mufflers and re works them for a louder sound. What i really Like about them is the easy to change baffles to change the sound (have to quiet it down for the on base inspections).

The point is, I was disappointed to find that they are unable to rework mufflers for the Street Bob. This is direct from their site:

"We do not offer a solution for the Fat Bob®, Street Bob® and 2010 Wide Glide® models"

Is there really that large of a difference in the stock exhaust between the above mentioned models and the other Dynas?

Here is the site if you want to check it out for yourself:
