Construction & Design:

The header is constructed from heavy duty 16 gauge 409L stainless steel, chosen for its excellent strength and resistance to rust and corrosion. The mandrel bending process maintains consistent tubing diameter throughout bends, promoting optimal exhaust gas flow and reducing backpressure. The ceramic coating applied to the header not only protects against extreme heat but also helps keep engine bay temperatures lower, which can improve overall engine efficiency and component longevity.

Precision laser cut port flanges, measuring 3/8 inch thick, ensure a perfect seal against the cylinder head, eliminating common issues such as warping or exhaust leaks that can degrade performance and cause noise. The design allows for a direct replacement of factory manifolds without any welding or modifications, making installation straightforward and reliable.

Performance & Sound

By improving exhaust scavenging and reducing backpressure, the Gibson Performance Header enhances low and mid-range torque and horsepower, which translates to better throttle response and more usable power during everyday driving and highway cruising. The ceramic coating also helps maintain cooler engine temperatures, contributing to consistent performance under demanding conditions. Additionally, the header delivers a more aggressive exhaust note, providing a satisfying sound upgrade without excessive drone.

Installation & Fitment:

This header is designed for a direct bolt-on installation on 2002 to 2010 Dodge Ram 1500 models, including Laramie, SLT, and ST trims. It utilizes OEM style connections and the stock crossover pipe, requiring no welding or custom modifications. The included premium gaskets and hardware ensure a secure, leak-free fit. Whether your vehicle is lowered or lifted, this header fits seamlessly, making it suitable for a wide range of builds and applications.
