Description

These Kooks 2-inch Long Tube Headers with High Output GREEN Catted OEM Connections are designed for the 2015-2026 Ford Mustang GT and Dark Horse models equipped with the 5.0L Coyote V8 engine. They are crafted from 304 stainless steel with 3/8-inch thick laser-cut flanges, featuring 2-inch mandrel bent primary tubes and 3-inch collectors with a patented scavenging spike. This system is engineered to provide superior exhaust flow and catalytic conversion, resulting in enhanced performance with claims of over 60 horsepower and 50 foot-pounds of torque to the rear tires. The high-output Green Cats are EPA certified and rated for forced induction applications up to 1000HP, offering increased horsepower output while maintaining regulatory standards (excluding California).
