Update June 16, 2012. I've managed a couple of flights since installing the sound insulation. The first flight was after some Bing carb adjustments and it seemed like the engine was running smoother. Later I realized it was the sound insulation, duh.
Just completed another flight and the Thermo-Tec Suppressor mat has reduced the engine and dual exhaust significantly.

I've been meaning to add a barrier under the cabin floor to deal with the noise and heat created by the dual exhaust on the Jabiru. Here is my solution, untested to date, waiting for the weather to clear.
Had some .016 aluminum sheet, 2'x4' (609mm x 1218 mm), used 2' as length and cut 2 pieces to match the fuselage bottom. Attached some Thermo-Tec Suppressor mat to the sheets of aluminum and then installed using stainless sheetmetal screws. The fiberglass wing root fairings held the outside edge and a few SS screws along the inside to keep in place.
The pilot side ready to be installed.
