     Hi Bill,
     What I am proposing is to use the springs on the 4 corners of the muffler, i.e, suspend the muffler.  This idea is for mufflers mounted under the
     fuselodge, not in the engine compartment.  This is an effort to remove the muffler harmonics from the floors of the aircraft.  I HOPE that the
     springs will get enough airflow to keep them from overheating.
