Hedman 1-5/8” HTC Coated Long Tube Headers for 1978-1979 Ford Broncos with 351-400M Engines.

Hedman Long Tube Headers use mild steel, smooth-flowing, CNC mandrel bent tubes to allow your Ford Bronco’s 351-400M engine to breathe easily. The Long Tube design provides a substantial exhaust flow, which produces higher amounts of horsepower and torque, an upgrade that you’ll feel. These Headers have a high-temperature polished ceramic HTC Coating that resists corrosion and withstands temperatures up to 1400 degrees F.
