    All Budget Headers are NOT Created Equally!
    Hooker's Competition Series Headers come in your choice of finishes and are engineered to perform at a reasonable price! To let your engine really breath Hooker utilized 16 gauge (.049'' thick) steel tubing attached to long transition style collectors! Giving you a serious increase in flow over other brand headers without a loss in the backpressure most engines need to perform! After years of testing, Hooker has discovered that a machined 5/16'' header flange offers enough flex to hold the gasket tight to each exhaust port, and enough rigidity to keep everything properly tied together.


    Features:
  • Mandrel-bent tuned-length tubing for smooth exhaust flow and power
  • Sturdy 16 gauge steel tubing
  • Perfect seal 5/16'' machined header flanges
  • Long transition collector for improved power over standard headers
  • Comes with gaskets and bolts Reducers sold separately.
