Construction & Design:

These mid-length headers are crafted from premium mild steel, chosen for its balance of strength, heat resistance, and cost-effectiveness. The 18-gauge tubing is mandrel bent to maintain consistent diameter and smooth exhaust flow, reducing turbulence and backpressure. The thick 3/8-inch header flanges are precision-cut using CNC waterjet technology, providing a perfect mating surface that ensures a tight, leak-free seal with the cylinder heads.

The headers feature 1-7/8-inch primary tubes that transition smoothly into 3.00-inch collectors equipped with merge spears. This design promotes efficient scavenging and exhaust velocity, which can contribute to improved engine breathing and throttle response. The inclusion of O2 sensor bungs in both collectors allows for easy integration with factory or aftermarket oxygen sensors without any additional modifications.

Installation & Fitment:

Installation is straightforward with these headers, designed for a direct bolt-on fit to the 1974 Dodge Ramcharger equipped with a Gen III Hemi engine swap. They bolt directly to Hooker BlackHeart BH2467 or BH2468 exhaust systems, simplifying the exhaust setup. The headers provide ample clearance for critical components including the brake booster, steering shaft, power steering box, and starter on both left and right sides. They are also compatible with multiple automatic and manual transmission options, ensuring broad application without the need for custom modifications.

Hardware and detailed instructions are included to facilitate a hassle-free installation process, making these headers an excellent choice for both professional installers and experienced enthusiasts.
