anyone used these sound deadening products? the fatmat stuff is supposed to be more oriented towards what im looking at.

looking at quieting the interior noise from loud exhaust. what is your opinions? worth it? not worth it?

thanks
 
I have a layer of Dynamat on the underside of the interior on the rear hatch, and also a layer on the exterior door skins and the interior door panel. Although the installation process is simple it will take a while. Getting a good bond between the mat and the sheet metal is the key to making work well.

It does work well. I did notice less road noise through the doors after installation. I also have far less rattle due to the sound system, which is why I installed it.

There are many different brand names out there, but last I shopped around they were all about the same $.

Good Luck

Yup, my entire interior has a layer of dynamat. I used the heat shield dynamat on the floor b/c my feet would get so hot from an o/r h I had on. That really kept the heat down. I used regualr dynamat in the hatch and thin dynamat on the doors. Overall, it helped a lot but did cost a good amount of coin. Good luck.
 
Try Peel and Seal. It's a roofing product that is MUCH chaper than either dynamat or Fatmat and is pretty much the same thing. It's available at your neighborhood Home Depot. The product consists of an asphault material sandwiched between an adhesive and an aluminum outer surface. I used it extensively on one of my british cars during its restoration. Very happy with it. The price will make you giddy after pricing the top shelf stuff. Good luck!

I've used this in my car as well. I got it at Home Depot and it costed about $12 for a 6" x 16' roll. It adheres to the metal real well when it's decently hot out and it DOES NOT STINK like many people think it would, being a roofing product and all. It does the job real well too. I have it in the rear of my hatch and on the inner door panels. Once I gut my interior to put the cage in I'm going to do the whole car with this stuff. I'm very happy with it.

here's a pic of it layed down in the hatch.

i have my whole car dynomatted cieling down to the ground doors everything, i think it helps but is it the end all answer no. I had alot of it laying around so thats why i used it, its not cost effective at all and the roofing material looks like the way to go, thanks for sharing that. :nice:

vristang & ol'whitey - how much weight did these products add to your car?

Couldn't say. I think I had less than a roll on the rear hatch, no clue on the doors. It was nothing compared to the 2 15" & 2 8" subs, amps and sealed boxes.

The best way I can think of to estimate the weight added to the vehicle is based on what a roll of a given material wieghs and how much area it covers.

The upside is that all that extra weight is a great way to justify a stroker motor:nice:
