Unlock the full performance potential of your 5.0L Coyote engine with this Kooks Header and Catted Connection Pipe system. Engineered to replace restrictive factory manifolds, these headers utilize 1-7/8 inch primaries to significantly improve exhaust scavenging and flow.

Each set is handcrafted in the USA and dyno-tested to ensure maximum power gains across the RPM range. The system is finished with precision-engineered flanges for a leak-free seal against the cylinder head.
