I am tempted to duplicate your endeavor!
I noticed an improvement in noise reduction just with the panels. I tried some foam in a few areas to see what kind of dampening I would get. I have a feeling that if I get some self-adhesive weather strip and place it along the inside edges all around, I will see less vibration on the outside edges. The vibration with out dampening isn't that bad, but every little bit helps when quieting these motors. A different intake setup is my latest endeavor. I'll be ever-tinkering with this thing...as you know, perfection takes time.
