Hedman Hi-Tech Coating (HTC) Hedders


Do you drive your vehicle in extreme high heat conditions such as when racing or towing? If you answered yes, then replace your power-robbing stock manifold with Hedman Hi-Tech Coating (HTC) Hedders to lower your operating temps and release extra horsepower and torque from your engine.

Hedman Hedders have always been made in the USA since the company was founded over 50 years ago. Back in the 1980s, Hedman pioneered the use of ceramic metallic coatings for Hedders after observing its use in the aerospace industry. Bob Hedman started out making Hedders as a one man shop but word spread fast about the horsepower and torque that Hedman Hedders were producing. His Hedders have been in demand by top engine builders and racers since the start. Hedman’s time perfecting Hedders on the track and on the dyno ensures you will get optimum performance with every Hedman Hedder whether it is installed on your race car or daily driver.

  • Handles temps up to 1,400 degrees and protects from corrosion with ceramic metallic coating
  • Proudly manufactured in U.S.A.
  • Perfect for towing vehicles and motor homes
  • The ceramic metallic coating can withstand high-heat situations like racing or towing 
  • Keeps under hood temps lower
  • Will not chip, peel or turn blue like chrome

NOTE: Not legal for use or sale in California on vehicles that came equipped with emission controls from the factory.
