With engine running and tranny in park/neutral, have the wife or someone
sit in the pilot's seat and raise the rpm as you stand back aft and
check the exhaust flow by feel against your hand and by sound. If you
hear a high wispy sound instead of what you know to be normal, then that
is an indicatore you're dealing with constipation.

But then you have to determin whether or not it is the Cat or the
Muffler...
