    Notes:
  • Will not fit turbo 400 applications

    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%).

    Features
  • Reducer Flex-Tubes
  • Reduces Backpressure
  • Improves Engine Efficiency
  • Hardware and Instructions Included

    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 the universal kit, systems do not include mufflers. Hooker recommends using Super Competition Turbo, Aero Chamber, Maximum Flow, or Competition Turbo mufflers with a 2.25" offset inlet/center outlet configuration.
