Construction & Design

The Gibson Performance Header is constructed from heavy duty 16 gauge 409L stainless steel, known for its excellent durability and resistance to rust and corrosion. The ceramic coating applied to the header provides high-temperature protection up to 1300°F, which helps reduce engine bay heat and extends the life of the header by preventing oxidation and wear.

Precision laser cut port flanges at 3/8 inch thickness ensure a perfect, leak-free seal against the cylinder head, eliminating exhaust leaks and flange warping common with lesser quality headers. Mandrel bending technology preserves the tubing’s diameter through every curve, promoting optimal exhaust gas velocity and improving overall engine efficiency.

Performance & Sound

By improving exhaust flow and reducing backpressure, this header enhances the engine’s breathing capabilities, resulting in increased horsepower and torque, especially in the low to mid-range RPMs where most daily driving occurs. The ceramic coating helps maintain cooler engine temperatures, contributing to improved engine longevity and consistent performance. Additionally, the header produces a more aggressive yet refined exhaust tone that enhances the driving experience without excessive noise or drone.

Installation & Fitment

The Gibson GP312S-C is designed as a direct replacement for the factory manifolds on Dodge Ram 1500 SRT-10 models from 2002 to 2010. It installs using the stock crossover pipe and OEM style connections, requiring no welding or custom fabrication. This straightforward bolt-on installation makes it accessible for professional mechanics and experienced enthusiasts alike. The header accommodates both lowered and raised vehicle setups, ensuring versatile fitment across various builds.
