Hey Bobby, glad to hear you got down safely.  Having two alternate runways available was indeed a blessing … the 360 is not doable in most situations.

Like many others as you say, I too have a Hush Power II … mounted under the belly, aft of the firewall; there is probably 4 feet of pipe ahead of my muffler and 2 afterwards.  So far all inspections on my muffler have not revealed any loose material within … but I’m low-time 48 flight hours, maybe 55 hrs if you include ground-running.  Incidents like this do make a guy think.  I find my installation so loud as it is that I can’t imagine operating without a muffler …
