Increasing the conduction surface and convection surface area of the heat
muff is the solution.  Tony Bengalis has a simply elegant idea.  Buy two
long springs from the hardware store.  The kind you use for back porch
screen doors.  They now have a threaded bolt on one end and a embedded nut
on the other.  put the two together and then place one end in the vise and
stretch that rig to about 15 feet or so.  remove the heat muff shield to
expose the exhaust pipe.  Drill two holes on each flange  of the muff area
and use stainless steel machine screws to fasten one end of the spring.
Wrap the spring around the pipe making sure there is a tight contact to the
pipe for good conduction and secure the loose end to the other flange.
Install the muff cover and you are finished.

The results are increased metal surface area to heat up the air moving
through the muff and increased conduction by metal to metal attachment.
