Construction & Design

This header is crafted from heavy-duty 409L stainless steel, known for its excellent resistance to rust and heat. The 16-gauge tubing is mandrel bent to ensure smooth bends and consistent diameter, optimizing exhaust gas flow and reducing backpressure. Precision laser cut port flanges at 3/8 inch thickness prevent warping and guarantee a tight, leak-free seal against the cylinder head.

The entire assembly is finished with a high-temperature ceramic coating capable of withstanding up to 1300°F. This coating protects the metal from corrosion and thermal fatigue while reducing engine bay temperatures, which contributes to improved engine efficiency and longevity.

Performance & Sound

By improving exhaust flow, the Gibson Ceramic Coated Performance Header enhances your Dodge Ram’s horsepower and torque, especially in the RPM ranges most used during highway cruising and everyday driving. The improved breathing reduces engine strain and heat buildup, resulting in cooler operating temperatures and sharper throttle response. Additionally, this header delivers a more aggressive yet refined exhaust note that enhances the driving experience without introducing excessive drone or harshness.

Installation & Fitment

Designed as a direct bolt-on replacement for the factory manifolds, this header installs easily using OEM style connections and the stock crossover pipe. No welding or custom modifications are necessary, making installation straightforward for both professional mechanics and experienced DIY enthusiasts. Basic hand tools are sufficient to complete the upgrade.
