    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)

    Rated 4 out of 5 by from Hookers on a Vette, classic! What can you say... peanut butter and jelly. One small issue, the welds were heavy on my set and are in the flow path, I'm going to clean them up prior to install. Good stuff for the money. They fit great.
