They may not even make this now but I used Thermotech on my Cobra. Easy to cut, bends as easily as a blanket and it will withstand up to 1500 degrees. I even had my transmission tunnel lined with it and worked great. It came in a roll and you just unroll it and either glue it in or use screws. I think it was about 1/4 inch thick with the shinny side out. I even replaced some of my aluminum heat reflectors with it as it lowered the temperature behind the shield more than the aluminum did.
