• 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.


  • Fits 2014 & up GM Gen V LT1/LT4 Engines
