1) Dynamat/Dynamat Extreme
2) Brown Bread, other B-Quiet Products
3) Generic E-Bay brand
I don't know about the generic brand. My brother has told me good things about Brown Bread, but I do not have direct experience with that. I DO have experience with the Dynamat product. It attaches directly to the metal parts of your car and does a very good job of deadening sound. For example, I put a couple of strips in the roof of my Turbo Buick and when you tapped on it before the Dynamat it sounded hollow and tinny. After the install, it sounded solid and not tinny at all.
It also improves the sound quality of your stereo system. It does add weight however, so I wouldn't go nuts with it. There are some people that add hundreds of pounds of it to their cars. I'm sure it makes it "tomb-like" but I wouldn't want that much extra weight.
