• Manufactured from high-temperature steel core/graphite faced exhaust material.
• Expanded steel core provides stability and maximum torque retention to eliminate gasket failure.
• Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head.
• Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load.
• Can be trimmed if necessary for modified port applications.
• For OE replacement, high performance street, drag race and oval track use.
