The Header Armor exhaust manifold heat shield, exclusively from Heatshield Products, is engineered to reduce under-hood temperatures by up to 70%, lower air intake temperatures, and unlock more horsepower—whether you’re at the track or cruising the streets. Featuring exclusive BioCool insulation, it withstands continuous temperatures of up to 1,800°F and spikes of up to 2,200°F, outperforming traditional exhaust wraps while emitting minimal smoke after installation. Designed for effortless installation, Header Armor can be easily cut with heavy-duty scissors and wrapped around headers without removal in most vehicles, delivering the easiest, longest-lasting protection for your headers and enhancing your vehicle’s performance.

FAQ

What is Header Armor, and how does it improve engine performance?

Header Armor is a heat shield that helps your engine produce more power by retaining heat within the headers and exhaust system. This increases exhaust gas temperatures and velocity, improving exhaust flow, scavenging efficiency, and overall engine performance.

How is Header Armor different from traditional header wraps?

Unlike header wraps, which completely enclose individual header tubes, Header Armor uses a single shield (or customizable segments) to cover one side of the primary tubes. This design reduces 50% more heat than exhaust wraps and up to 80% more than ceramic coatings while still allowing the tubes to breathe.

What are the benefits of using Header Armor over ceramic coatings?

Header Armor offers superior heat reduction compared to ceramic coatings, lowering under-hood temperatures and improving performance. Additionally, it helps maintain most header corrosion warranties since it allows airflow around the pipes, preventing moisture buildup and corrosion.
