Dear Paul
     Here is what Jeerys muffler looks like any comments good or bad
etc. It's built out of 321 s.s except for the end caps and mounting
flange.

Regards

Looks great Ed. Should simplify under the cowl greatly.

Ops forgot to send the pictures.

It does look great.  Ed is an exceptional craftsman.  I am really
looking forward to bolting this on  my engine.   I wish there was a
running rotary project near by to test it on.   Anyway,  this is a zero
back pressure muffler.  The area of the tailpipe  is greater than the
area of the two  exhaust pipes.  At no point is the flow of exhaust gas
restricted.   The exhaust gas, it is hoped, will slow down and become
disorganized inside the  muffler.  That should quiet it down.  The cool
tube should cool it down.  This exhaust system will not conflict with
the Schertz Beam engine mount.  It clears the intake runners with
plenty of room.   The tailpipe exits the cowl at the 4 o'clock
position, well away from the rad and oil cooler mounted  underneath.
The exhaust pipes are fully welded on the back side of the exhaust
flange and tack welded on the outside to allow room for differential
heat expansion.         Jerry
