Notes: - Will not fit manifolds that exit straight down.
- Models with more than a 131.5" wheelbase must use a tailpipe extension kit to provide proper tailpipe exit. Tailpipe extensions will need to be fabricated or ordered from a local muffler shop.
- All systems come without mufflers. Hooker recommends using the following mufflers with a 2.25" offset inlet/center outlet configuration:
Aero Chamber - 520-21501
Maximum Flow - 520-21601
Competition Turbo - 520-21005

Hooker Headers Competition Dual Exhaust Kits are designed to fit specific applications using Hooker Competition Headers or stock exhaust manifolds. They have 2.25" diameter 16-gauge aluminized steel tubing that's mandrel-bent to maintain a consistent inside diameter for maximum flow (press bending crushes the pipe, which can reduce volume by more than 10%).
