Notes

Header dual system will not fit Turbo 400 applications.

P/N 16521HKR was designed to be used with Hooker Competition P/N 2456HKR headers.  If the dual exhaust is being installed with any header other than 2456HKR, modifications will be required.  Hooker Headers will not assume responsibility for fit or performance.

Mufflers are not supplied with this system.  Hooker Headers has designed this kit for use with Hooker Turbo mufflers P/N 21005HKR, 21105HKR or any equivalent 2-1/4" i/d inlet by 2-1/4" i/d outlet single offset muffler.  Glasspack mufflers may be used with slight modification.
