    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.
  • 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)

  • 2453-1 - Hooker Headers Competition Headers Chevy/GM Truck is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from GM small block headers This product is one of the best buys I've purchased. Minor modification to motor mount that's it. Awesome sound and looks great under the hood. Unfortunately the motor is no longer. Any suggestions on my replacement would be great. 1986 gmc serria Classic c-10. It was not the original motor.
