Hooker has created a full line of adapter tubes that fill the gap and include all hardware and gaskets for a clean and simple connection. When connecting Hooker Mid-Length Headers for the 67-69 Camaro/Firebird and 68-74 Nova to our full exhaust kits, an adapter pipe is required to fill that gap between the end of the headers and our Hooker exhaust systems (which are designed to work with Mid-Length header systems).


  • Designed to connect header numbers 2475HKR, 2476HKR, 2477HKR to our Hooker 42503HKR and 42505HKR 2.5" exhaust systems
  • Connects Mid-Length headers to Hooker exhaust systems
  • Includes adapter tubes, 2.5" heavy duty band clamps and O2 sensor bung plugs
