Do you have any good car audio shops where you live?? The product is made by Dynamat and is called Dynaliner. It is specifically made to replace your hood liner and has sound deadening + flame retardant properties.
You can custom fit it to any car. I'm not sure if they have any vehicle specific kits or not. It is made by a company in Ohio. The hood liner in my Mustang was trashed so we replaced it with the Dynaliner product. We also put the Dynaliner in the roof between the liner. That plus 4 1/2 cases of extreme Dyanamat on every inch of the car. Even with a supercharger, JBA Firecone headers, high-flow cats and a Borla Cat back exhaust system the car is pretty quiet inside compared to what it was.
I actually started modifying the car because I had so much weight added to the car from Dynamat and stereo equipment that I noticed the car didn't have enough power anymore. My friend owns a stereo shop so that was my first car hobby. If you have trouble finding it I can give you my friends number and maybe he can get it for you because he is an authorized Dynamat dealer.
