Subject: [FlyRotary] 20b Exhaust

I have fabricated my exhaust manifold/tangential muffler for my 20b.  All I
have left is to fit and weld the exhaust pipe.  I would like opinions on the
size the exhaust pipe should be.  This is in a pusher application (Velocity)
with a relatively short run from the muffler to the exit point.  Similar
installation to Al G.

Thanks,
Joe
