Application

Fitment Notes

• P/N 16526HKR was designed to be used with Hooker Competition Headers, 2453HKR. If the dual exhaust is being installed with headers other than 2453HKR, modifications will be required. We will not assume responsibility for fit or performance
• Mufflers are not supplied with this exhaust system. Hooker Headers has designed this kit in conjunction with Hooker Turbo Muffler (21005HKR) or any equivalent 2 ¼” ID inlet by 2 ¼” ID outlet single offset OEM muffler. Glasspack mufflers may be used with slight modifications.
• Breaking in an engine with ceramic-coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic-coated headers require several heat cycles to fully cure before they will withstand extreme heat. HOOKER recommends using a cast-iron exhaust manifold or an old header to break in new engines to avoid coating damage.
