Product Details

Hedman Hedders 28146 HTC coated exhaust headers deliver superior performance and durability for classic Pontiac V8 applications. These headers feature Hedman's advanced HTC (High Temperature Ceramic) coating, a ceramic-metallic finish that bonds to the header tubes with over 10,000 PSI of strength, providing exceptional protection against the extreme heat and corrosive elements that destroy uncoated headers.

HTC Coating Benefits:

  • Superior thermal insulation keeps exhaust gases hotter for increased velocity and horsepower
  • Reduces under-hood temperatures by containing heat within the tubes
  • Will not flake, chip, or peel like chrome or inferior coatings
  • Resistant to abrasions and road chemicals
  • Thermal protection rated to 1400°F
  • Easy to maintain and clean

Hedman pioneered the ceramic-coated header in the 1970s and has perfected the process over decades of development. These headers are engineered specifically for Pontiac 326-455 cubic inch V8 engines and are backed by Hedman's 5-year warranty against external rust-through. The HTC coating not only delivers a premium appearance but provides the functional benefits of improved exhaust scavenging and engine bay heat management that serious enthusiasts demand.

Good service,delivery was on time.

You guys are wonderful

Excellent service and fast shipping. A seller I would do business with again.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

User- friendly web-site

I saved over a hundred$ on a set of electric cooling fans. so the prices r great but it took 4 days to process and ship my order so well see how long it takes to get here but overall I would rather save money than get fast shipping

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
