Two glasspackes in one, cool idea! i would love to hear it too. I had glasspacks on my truck with 2 1/2 and i didn't think it was loud at all, i beleve they were 20" and were louvered like what is inside your dual glasspack.

EDIT: Just got to thinking that it looks used inside, did you buy it used? also where did ya buy them? The sound clips on the webpage woung great! deep and throaty.
