I just picked up a Buell race muffler too. I have been told they are just as deep as my Hawk but a little quieter. I am sure there is a difference in sound between the xb and tubers with a race muffler... single vs dual outlet. I think the tinny sound is from being so free flowing and open. I am no expert but I did fire my bike up with no muffler and its was LOUD and CRACKLEY. Hehehe.
