Exhaust heat shield blanket (1/4" thick)
677004-0000
Wrapping headers with Header Armor™ keeps heat in the exhaust system and out of the engine compartment. This lowers underhood temperatures, helping with overall engine cooling and with less heat being transferred to the passenger compartment through the firewall. Header Armor™ also results in hotter and faster-flowing exhaust gases, which creates a scavenging effect to pull intake gases through the system quicker. This lowers intake temperatures, resulting in more power. The abrasion-resistant Header Armor™ material cuts effortlessly with heavy-duty scissors, making it simple to install. It wraps around header pipes of small or large diameters, and removal of the headers is not necessary for installation on many vehicles.
Header Armor™ is capable of withstanding a continuous 1,800 degrees F, with intermittent spikes of 2,200 degrees F. We use either a ¼-inch or ½-inch BioCool thermal barrier bonded to heavy-duty foil. BioCool is a non-caustic, non-flammable thermal barrier. It does not cause itching and won’t smoke or smell the first time it is heat-cycled. In addition to being abrasion-resistant, Header Armor™ has an aluminum layer that is chemical-resistant and lasts longer than other exhaust wraps. Because it does not wrap around the entire header, it is compliant with most header manufacturers’ warranties. Kits are available for single headers and pairs of headers, and all kits include a small spool of HP Tie Wire™ to secure the Header Armor™.
