Notes:
Will not fit turbo 400 applications
This dual exhaust system was designed to be used with Hooker Competition Headers - 520-2456. If the dual exhaust is being installed with any other headers modifications will be required. Hooker will not assume responsibility for fit or performance.
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%).

Notes

The original equipment tailpipe exit location is retained on most systems unless otherwise noted below in More Info
For racing use only (not legal for use on vehicles originally equipped with catalytic converters)
Except for the universal kit, systems do not include mufflers. Hooker recommends using Aero Chamber, Maximum Flow, or Competition Turbo mufflers with a 2.25" offset inlet/center outlet configuration.
