    All Budget Headers are NOT Created Equal!
    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 breathe, 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 plus 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
  • Gaskets and bolts included (Reducers sold separately)
  • Available in five finishes to suit your needs (see listings below for product availability) -

    Black Painted (Part numbers do not have a suffix)

    Metallic Ceramic Coating (Part numbers have a -1 suffix)

    Stainless Steel (Part numbers have a -2 suffix)

    "Darksides" Black Ceramic Coating (Part numbers have a -3 suffix)

    Titanium Ceramic Coating (Part numbers have a -4 suffix)
