Super Competition Sidemount headers deliver the most aggressive style and performance for your early Corvette. Sidemount headers are built from lightweight 18 gauge tubing. Sidetubes slip directly to the collector for a leak free seal. Replaceable Hooker mufflers are available separately in 2 different styles; glasspack and reverse flow. The glass pack style provides the highest performance with minimal backpressure and sound control. The reverse flow is designed for maximum sound control.

Features:

  • Tuned-length primary tubes for maximum exhaust scavenging and velocity
  • All necessary hardware included for a complete installation
  • Slip fit side tubes for leak-free seal
  • Designed for optimal performance
  • Industry’s best welds for durability
  • 5/16” machined flanges for a perfect seal
  • Long transition collector for decreased back pressure
  • Light weight & sturdy 18 gauge tubing
  • Mandrel-bent tubing for smooth exhaust flow
  • Replacement Hooker mufflers available in straight-through or reverse-flow versions
  • Requires use of motor mounts that locate the engine in the factory location

Instructions - 2224-34hkrrev1.pdf
Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty. Hooker long tube headers do not come with header reducers. Not compatible stock GM heads. Port size is 1.85" x 1.45".
