Review on 🔇 Dynamat 21100 DynaPad 32x54x0.452" Thick Non-Adhesive Sound Deadener: Quality Insulation and Noise Reduction Solution by Gregory Chaitanya

Unlike the Dynamat series which is really only good for high frequency vibrations such as ringing or knocking on metal. Not only is this Dynapad material amazing for the vibrations, but it blocks sound almost completely. Definitely watch their weight, it's very tight and very heavy which is great and that makes the soundproofing possible, but if you're installing the pad on anything other than the floor itself. Heavy duty glue won't be enough to hold it in place. I bought it for the back of my truck and luckily I was already planning on using the screws that were there for support. Those pillow blocks sound so good it's now quieter than the stock muffler and rear seats, and I didn't even put the rear seats in. I very much doubt typical cars will notice any real difference unless they strip it down to the metal. My truck is lowered, the exhaust comes out right behind the cab, there is a lot of noise in the cab. It was a dramatic difference. I also put an opaque layer of dynamite under the pad and ran it over it before inserting the pad and to be honest the dynamite added next to nothing to the sound, just a little tinkle here and there.
