snips...

Was doing my pre-Copperstate flight inspection yesterday and found that the
muffler had finally given up.  The wall had blown through where the header
tubes blast.  Fortunately  I had a SS heat shield over that area which kept
it from igniting the fiberglass cowl.  Tommorow's project is to kludge up a
quick & dirty "Swiss" muffler system (glass-pack style muffler slung under
the fuselage).  Don't have time to build a custom under the cowl muffler
before Copperstate.

That is not too bad for .035 thick SS :-)
I think you need to go up to 0.040 Tracy :-)
