Good morning Paul
Thank you for posting the photos
My message was intended for Ed and also for whoever else would care to
comment
By "observations" I meant: that now that Ed has used the exhaust for a
number of hours and on cross-country flights, he might wish to comment on
sound levels, apparent back pressure, etc...
Is Tracy Crook  using a similar design exhaust?
My Zenith is slowly coming out from under the snow where it was buried all
winter and spring fever is welling up in me!.

Tracy has a similar set up but both exhaust pipes converge into one larger
diameter pipe with a similar number of holes.
