    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 - Hooker Headers Competition Headers Chevy/GM Truck is rated 4.3 out of 5 by 6.
    Rated 5 out of 5 by from Badass headers Put these long tube hookers on my small block 350 and noticed a decent increase in power. Went from original exhaust to open headers and they sure make a difference. Hoping to get some mufflers soon though

    Rated 5 out of 5 by from Great product I'm happy with this product. I bought a month ago.
    Date published: 2016-08-25
    Rated 5 out of 5 by from Excellent product This product bolted right up and increased my horse power right away, no trimming or modifying brackets.
    Date published: 2015-02-15
    Rated 4 out of 5 by from Good quality and fit. I bought this for my 1987 K5 Blazer with a six inch lift. It's difficult to find a pair of headers that will clear the shackle hanger. These fit perfectly. The only modification needed was minimal grinding on the driver side motor mount to prevent possible contact.

    Rated 2 out of 5 by from Not impressed Paint can be better, remove from box (rusty), had to sand and repaint, other than that typical hooker heders.

    Will these fit a 1983 Chevy S10 with a 350

    Asked by: Venomx45
    No, depending on whether this is a 2wd or 4wd you will need these headers; 2wd - https://www.jegs.com/i/Hooker-Headers/520/2837/10002/-1
