Product Details

The Hedman Hedders 78056 HTC Hedders Exhaust Header delivers proven bolt-on performance gains in horsepower and fuel economy. Engineered with precision-mandrel bent tubing and robotically welded construction, this header provides superior exhaust flow compared to restrictive factory manifolds.

Key Features:

  • High-temperature ceramic coating for maximum heat dissipation and durability
  • Mandrel-bent tubing maintains consistent diameter for optimal exhaust velocity
  • Heavy-duty flanges machined for leak-free sealing
  • Backed by lifetime warranty against defects, cracks, and weld failures
  • Includes all necessary gaskets and mounting hardware for installation

Hedman's HTC (High Temperature Ceramic) coating provides excellent corrosion resistance and heat management, keeping underhood temperatures lower while extending header life. The precise tube routing ensures proper ground clearance and maintains adequate clearance from starter motors, steering components, and chassis components. This header is designed for direct bolt-on installation using factory mounting points.
