  I doubt it makes much practical difference.  The heater lets it start
working in say ten seconds instead of say 90, but doesn't do anything after
that.  It lets them move the sensor to the cat housing instead of the
collector pipe without worrying whether it's going to stay hot enough --
but you're not going to do that anyway.
