Lizard Skin! It sprays on like pick-up truck bed liner and works basically the same way by absorbing vibrations (like putting your hand on a drum to silence it). They also make a second product with water glass (sodium silicate) in it to become a thermal barrier, but you still need the second product to quiet down the noise.

Grace Ice Shield from Home Depot is just about the same as Dynamat. Google it, you'll find lots of reports.

I read the specs on the Boom-mat, Dynamat and Eastwoods X-mat and ended up buying a lot from Eastwood just because they had a great sale going on. (I've also laid down some 'Hushmat' brand in the past - they are OEM suppliers)

I have to say, the X-mat appears to be just as good as the others. I ended up also buying the DEI brand Under Carpet stuff as well for an added heat barrier..
