Three clips of my Buell X1 as I replace the original (old) muffler with a new D&D race muffler. The first clip is the stock muffler, the second is the bike with no muffler at all (sounds real nice, but very loud), and the last clip is with the D&D muffler installed.
The description states it's "a tad loud", and I think that's an understatement. I believe it is only about 10% quieter than with no muffler! I haven't re-calibrated the fuel injection to compensate, so it runs a big rough. It's loud, feels punchy, but maybe too loud for residential streets?
