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, which helps maximize engine efficiency. The 3/8 inch thick laser cut port flanges provide a precise, leak-free seal against the cylinder head, eliminating common issues like warping or exhaust leaks.
Its ceramic coating not only enhances durability but also helps reduce under-hood temperatures by reflecting heat away from critical engine components. This coating is rated to withstand temperatures up to 1300 degrees Fahrenheit, ensuring long-lasting protection even in demanding off-road or high-performance driving conditions.
