Eastwood Thermo-Coustic Sound Deadener Material
Product Review (submitted on November 1, 2010):
Just installed on the floorboards and firewall in my 71 Charger with headers. Sound wise a big difference. As far as heat reduction, so-so. The driver's side firewall by my gas pedal gets to 180º during summer driving with the headers a few inches away from the firewall. With the Eastwood product it was reduced to 140º. The video only shows 20 seconds of heat on the metal. In the real world your driving your car for a longer period and with the constant heat from the headers (if your car has them)you probably won't see the same results as the video.
