Construction & Design
The Gibson Performance Header is constructed from heavy duty 409L stainless steel tubing, chosen for its excellent strength and corrosion resistance. The 16 gauge tubing is mandrel bent to ensure smooth, unrestricted exhaust flow, maximizing engine efficiency and power delivery. The thick 3/8 inch laser cut port flanges provide a precise, leak-free seal against the cylinder head, eliminating common issues such as warping or exhaust leaks that can degrade performance over time.
The ceramic coating not only enhances the header’s durability but also reflects heat away from critical engine components, reducing under-hood temperatures. Rated to withstand temperatures up to 1300 degrees Fahrenheit, this coating ensures long-lasting protection even in demanding off-road or high-performance driving conditions.
Performance & Sound
This header improves the engine’s ability to breathe by optimizing exhaust flow, resulting in increased horsepower and torque primarily at low and mid-range RPMs. This makes it ideal for highway cruising and off-road torque demands. The improved exhaust flow also contributes to a cooler running engine, which can enhance reliability and throttle response. Additionally, the ceramic coating helps dampen heat-related noise, providing a refined exhaust tone without excessive drone.
Installation & Fitment
The Gibson Performance Header is a direct bolt-on replacement for the factory exhaust manifolds on Jeep Wrangler JK models from 2007 through 2011, including Rubicon, Sahara, Sport, Unlimited, and X trims. It utilizes OEM style connections and retains compatibility with the stock crossover pipe, eliminating the need for welding or custom modifications. Installation is straightforward and can typically be completed with basic hand tools, making it accessible for both professional installers and experienced DIY enthusiasts.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
