Construction & Design:
The Gibson Performance 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 maintain consistent diameter and smooth bends, optimizing exhaust gas flow and reducing backpressure. The laser cut port flanges are precision engineered at 3/8 inch thickness to prevent warping and ensure a tight, leak-free seal against the cylinder head.
The entire header is finished with a high-temp ceramic coating capable of withstanding temperatures up to 1300 degrees Fahrenheit. This coating not only protects the metal from corrosion and thermal fatigue but also helps reduce engine bay temperatures, contributing to improved overall engine efficiency and longevity.
