Harley-Davidson motorcycle riders understand thunder, especially in the context of Samson high performance slip-on  mufflers. Samson “Rolled Thunder” mufflers produce the traditional sound and performance that American riders demand. The sophisticated look of the rolled edge muffler body adds a big batch of class to any Harley-Davidson Softail or FLH motorcycle.
