This clip is of Brian Trubee RV4 with a coax muffler.
IMHO it is less annoying :)

For comparison here is an assortment of rotaries.
Mike W. NA 2 rotor, Dave L. 13B turbo,  Al G. NA 3 rotor.

Agreed, the new muffler sound is much more appealing. Will incorporate that design as
a second stage. Should end up being very tolerable, square tube spiral/can up front,
long eductor on the bottom.
