    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 Aero Chamber, Maximum Flow, or Competition Turbo mufflers with a 2.25" offset inlet/center outlet configuration.
