FYI: The Viking Exhaust by Paul Bryant can be ordered with different length muffler. He will make it standard length or any length you preferer. The silencer in the standard length muffler is only about 5 inches long. I packed the silencer on
@vsteel bike with muffler fiberglass packing and it helped reduce the sound just a little bit, but noticeable. If you ordered a longer muffler with a longer silencer, I may help even more.
