The dyno run sounds pretty close. McKraut's sound fantastic in person. I mean, really really really good. Loud, sure, but the sound is delicious so its not unpleasant. It doesn't sound like some straight pipe Harley's where the tone is more flatulent than anything. Speaking of which...
there's no place for exiting gas expansion....
Ya loosen your belt a little bit, and things should take care of itself.
