Hedman Hedders 69446 HTC Coated Exhaust Headers for Chevy GMC Pickup Truck

Hedman Hedders 69446 HTC exhaust headers combine superior performance with long-lasting protection for 1988-1995 Chevrolet and GMC pickup trucks. Engineered for 5.0L and 5.7L engines in both 2WD and 4WD applications, these headers feature Hedman's exclusive HTC (High Temperature Ceramic) coating that delivers both functional and aesthetic benefits.

HTC Coating Technology:

The proprietary ceramic-metallic coating bonds to the header tubes with over 10,000 PSI of adhesion strength, creating a barrier that withstands extreme temperatures and corrosive road conditions. Unlike chrome or powder coating, HTC will not flake, chip, or peel over time. This advanced coating insulates the exhaust gases within the tubes, maintaining higher internal temperatures for increased exhaust velocity while simultaneously reducing engine bay heat.

Key Features:

• Compatible with 1988-1995 Chevy/GMC 1500, 2500, and 3500 series trucks with 5.0L or 5.7L engines
• Fits both 2WD and 4WD configurations including Avalanche, Sierra, Silverado, and Cadillac Escalade EXT models
• Thermal protection rated to 1400°F for extreme durability
• Resistant to chemical exposure and physical abrasions
• Low maintenance finish that's easy to clean and maintain
• Backed by Hedman's 5-year rust-through warranty

Hedman pioneered the coated header market in the 1970s and continues to refine the HTC process for maximum performance and longevity. These headers provide measurable gains in exhaust flow efficiency while protecting your investment with industry-leading corrosion resistance.
