I'm pretty close to finishing my plane, just getting the paperwork
assembled for
registration and then inspection.
 I was up working on it when one of the other tennants stopped
by to compliment me on the looks of the metal cowl. He said it
looked really nice with a cowl like that, but that it should
sound more "Macho". He said it was too quiet, when I'm running
it all he can hear is the fan in front.
 It's got 2" diameter pipes into a "y" 32 inches back from the exhaust
ports, then into a
Hushpower muffler and then out to the side and bottom under the
wing. It has the jspec 13BREW motor with no exhaust port baffles.
 The prop is a Catto 74" dia x 88" pitch.

 I wish there was a way to lower the tone. I am thinking hard on that
problem.

5000 W stereo and speakers? :)
Are you still running twin turbo's? Just wondering with the 13BREW comment.

Brian's airplane is NA Tom.

It seems like separate stacks, one from each rotor, pointed in
different directions would lower the tone. It would certainly lower
the frequency of the output pulses.
Then again, I'm not convinced it would be an improvement to lower the
tone. My opinion is that people aren't used to the sound. Making it
more big-fart Continental/Lycoming-like isn't better, just familiar.
I think we need to get more people exposed to the smooth and powerful
sound of not reciprocating..
I do think it would be better for the engine to not sound like a two
stroke, which I think some people may unfortunately associate with the Wankel.

Matt,
I had a 1973 RX 3 that I terrorized Edmonton in. I finally broke the stoke
exhaust by getting it to back fire on deceleration. An officer pulled me
over and gave me an inspection ticket to have it repaired in one week. The
factory parts were expensive. At the time the racers were using two straight
pipes 11 feet long. I thought this was a good idea, and got a muffler shop
to bend me up a couple of pipes and two quiet mufflers. It sounded like two
chain saws at full bore. It finally shattered one muffler in the Rogers Pass
(Canada west of Lake Louise), into 1/2 inch pieces. When I got it home I was
almost deaf for a couple of days. Made a new pipe that was collected and 2"
out the back. Much quieter!!
