The Hedman Hedders 66104 HTC (High Temperature Coating) Exhaust Header delivers superior performance and lasting durability for high-performance engine applications. This exhaust header features Hedman's proprietary HTC coating technology that provides thermal protection up to 1300 degrees Fahrenheit, making it ideal for demanding street and racing applications.

Key Features:

  • High-temperature ceramic-based coating protects up to 1300°F
  • Superior durability—will not chip, peel, blue, or discolor
  • More resistant to corrosion and damage than traditional chrome plating
  • Enhanced heat insulation keeps engine bay temperatures lower
  • Easy to clean and maintain for long-lasting appearance

Hedman's HTC coating represents the best high-temperature coating available on the market today, combining exceptional heat management with a durable, attractive finish that outperforms traditional header coatings. This header is engineered to improve exhaust flow, reduce backpressure, and increase horsepower while maintaining its appearance and integrity under extreme conditions.

Ordered Borla headers 17216 that was lowest price on internet. Shipped fast at a fair price and arrived in good condition. Communication from Autoplicity was timley and accurate with tracking number. I would not hesitate to order from them again.

There.was a bit of miscommunication between sales and shipping departments, but my order was filled and shipped as stated. Very low price, in fact the lowest on the net, and I did alot of research. Other than the shipping issue, I'm very satisfied and will buy more parts from them soon. Thank you!!!
