Thanks for the input everyone. The front of the muffler
can be supported from the motor mount. The rear muffler mount is the dilemma. I
hate the idea of an external doubler but I think it really needs
one.

Mine is less than 1" from the belly to keep it in the turbulent
slipstream behind the cooling exit and avoid drag. A .007" thick piece of
SS heat shield is riveted to the belly in this area. The SS expands when
heated and creates its own airgap for insulation.

I've had the plane down for a few weeks
making several changes. I would like to move my muffler out of the cowl to the
airframe belly. How much space should I leave between the top of the muffler
and bottom skin? My exit fairing hangs down about 5" below the airframe. What
have others done for heat shielding \ paint protection? Since the floor
pans are installed any riveting will have to be with blind rivets. Don't
really want to put a bunch of extra holes in the skin for this experiment. Any
advice or pictures would be appreciated.
Thanks,
