Ernest,
If there are just gasses leaking from the crack in the muffler then I
doubt it would trigger an alarm.  But if there are flames exiting the
muffler, that would be a totally different situation and it probably
would set off the alarm, provided the flames are in the line-of-sight of
the sensor.  A CO2 sensor might be a better choice for a leaky muffler.

Mark, would this detect a muffler crack?  If you have a push mower with
a worn out muffler, would it detect the 'un-muffled' exhaust gases?
