I got some sound deadner called Fatmat and just wanted to pass it on to others( website fatmat.com also sold on ebay) it is $49 for 36^ft and $99 100^ft they also sell kits 2. I got 36 of it. This stuff is almost identical to dynamat extreme. The only difference is that dynamat might be a tinny bit thicker but not much if at all. This stuff works great and is like $50 cheaper than dynamat.
