Looks interesting but there are a few questions in my mind. Dual exhaust for the muffler and exhaust pipe?, but the inside heat would still be maintained as there is nothing to draw the heat out and no way for fresh air transfers over the AVR and starter. The open bottom would still redirect/bounce the sound waves down then out.:h
I'm thinking(ouch another headache) that with the gas tank on top, there might not be a need for a top covering and just small openings around the corners of the tank to allow the sound waves to escape without causing a vibration of the tank and gas.
Now I need some Ice Cream to take care of my headache.

I guess you are writing about the GenTent design? Not sure about the reference to dual exhaust for the muffler and exhaust pipe - you are going to have to give me some glue to connect that topic as I am :h

My reference to the cardboard box and/or GenTent was more about sound reduction than the problems with air flow needed for cooling. I have previously stressed how air must flow and pointed out that sound abatement and cooling do not always complement each other. The compromise must be on sound reduction - not air flow. A fried AVR or melted engine is of no use to any of us. :) Small enclosures work well for sound reduction but any irregularity in air flow will cause an extremely rapid temperature rise in the engine.:(

The cardboard box experiment was only to prove that significant sound abatement can be accomplished with common materials - to go further takes a lot more in the way of fine tuning and analyzing the frequencies we need to abate.

You have apparently developed an understanding of many the factors and problems that one can encounter while designing a working enclosure. Yes, they can lead to extreme headaches. I've found that butter pecan ice cream does a better job than plain vanilla.:C
