Stock metal exhaust manifold shields reflect some heat, but they leave under-hood temperatures far higher than they need to be. Heatshield Products' Header Armor takes a different approach, wrapping headers and exhaust manifolds in a bio-soluble silica insulation that retains heat inside the exhaust path, drops under-hood temperatures, and keeps cooler, denser air reaching the intake.
BioCool technology sets it apart from wraps and coatings. The exclusive bio-soluble silica insulation core withstands continuous heat of 1,800°F and intermittent spikes to 2,200°F. That thermal tolerance exceeds what traditional exhaust wraps deliver, and because Header Armor shields one side of the primary tubes rather than fully enclosing them, the pipes still breathe, moisture does not trap against the metal, and most header manufacturer corrosion warranties remain intact.
Installation requires no header removal in most vehicles. Header Armor cuts to shape with heavy-duty scissors, wraps directly over the headers in place, and secures with the included wire or anchor hardware depending on the SKU selected. Available in 1/4-inch and 1/2-inch thickness options across multiple sheet dimensions, the product suits everything from inline-six applications to V6 and V8 header setups.
Paintable surface for a finished engine bay appearance. Any standard engine or exhaust paint bonds to the outer surface, so the shield can match or complement existing engine bay finishes rather than leaving a raw industrial look under the hood.
