Jim,
I don't know how to integrate a muffler into the system, but in terms of
ground cooling, a builder at ARR has an E-racer, with an IO-540,
supercharged, and cools it very effectively on the ground and taxiing with
the use of exhaust augmenters. He doesn't use a muffler, so his exhaust
(each side) goes into an augmenter tube, and this works VERY well. He can
run around on the ground as much as he wants to with no overheating.  In
flight, he gets 7-8" delta p depending on his air speed.
