Hi, Lynn and thanks for the response.  Any idea what type of decibles the
rotary would produce without a muffler, ie....straight pipes?  I don't know
what the spintech muffler DB measures behind Tracy Crook's aircraft.  Still
searching for a muffler that will stand up to the heat and pluses of a
rotary. Since I have a pusher, I don't want things coming out of the
muffler, as they would go through my prop. Not a nice thing.  Thanks again.
