Specifications
Headers, Super Competition, Side Mount, Steel, Painted, Chevy, 396, 402, 427, 454, Pair
Hooker Super Competition sidemount headers and mufflers deliver the most aggressive style and performance for your early Corvette, Camaro, Nova, or Firebird. Sidemount headers are built from lightweight 18-gauge tubing. Sidetubes slip directly into the collector for a leak-free seal. They are available in your choice of three finishes: Show quality chrome, high heat-resistant black paint, and metallic ceramic coating. The replaceable mufflers are available separately in two different styles: glasspack and reverse flow. The glasspack style provides the highest performance with minimal backpressure and sound control, while the reverse flow is designed for maximum sound control. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
