Dynamat or other types?
 

I'm at some point going to be recarpeting my IROC-Z and when I do, I was thinking of adding dynamat or a similar product undernear the carpet anywhere I could.

Has anyone tried this? Did it make a difference inside the car? I'm not going to run a stereo or anything, I just want the least outside noise coming into the cabin.

Is Dynamat the best product for the job or are there cheaper alternatives?

Dynamat works really good i used in my car less noise and vibration thats very good for a third gen.

if you want something cheaper or different i have ben planing to try some of there products.

There are many brands. Dynomax is really good but expensive. Raammat seems really popular and inexpensive.

Using some additional jute padding under the carpet and under panels helps alot too.

Search on eBay. I found a bunch of cheap "Dynamat clones" on eBay. I imagine that stuff is all about the same, as long as the thickness is comparable.

Yeah, I found the other style, called FattMat or something to that effect. Anyone had any experience with this style?

Certainly seems cheaper than Dynamat.

I used peal and seal (roofing material) stuff from lowes, it works pretty well all I hear now is wind noise from the seals at the door and window and some engine noise. It is real good about keeping heat out of the car, my pass floor board is no longer hot on the feet. I also used some of the forgot what it was called but its basiclly bubble wrap but made out of foil. I put it under the carpet behind the rear seats and on the gas tank/ axle hump. I used peal and seal under all the rest except under the seats I used 1 inch fiberglass insulation. I stuffed the fiberglass stuff in holes to. I think I spent all in all 60 on the insulation, including some expanding foam(mainly to keep bass rattles down). My new carpet had the factory jute padding on it also. When I re do my door panels in a few weeks I am going to put the foil stuff behind the panel.

check out second skin, the owner is very helpful and they have various different products for different needs

I've used FatMat and was fairly pleased with it. Since it's the first sound deadener I've ever used, I was not sure what to expect and have nothing to compare it with. There seems to be less noise in general, but I wish I had also gotten their sound deadening acoustical matt in addition to shield more noise. The FatMat went in well, stuck well and I am happy with the results.
