Paul,
Thanks, will do. Note that I changed out my exhaust port inserts to the n/a style. The n/a inserts don't have the diverter shelf to cut down on the shock wave. So, if this muffler works with my engine, it ought to work anywhere. Also, I feel the 3-rotor guys have an advantage here since our exhaust pulses are at a higher frequency (we get 3 pulses revolution vs. 2 per rev with 13B). I have a hunch that it will help to even out the exhaust so that the muffler won't be pounded as severely. From a decible perspective, it is "pretty quiet" (relative term). Anyone have a DB meter I can borrow?

Hi, Mark....congratulations on first run. I'm not far behind you. Need an
oil pan, radiator and a muffler. Speaking of muffler.....very interesting
concept you have there. That could be the answer to us canard pusher guys.
Looks like it could be made in a nice, small package. Please keep us
informed as to how this holds up to the rotary exhaust. Thanks for the
info, and continued good luck on your engine tuning, etc. Paul Conner,
