Kooks only uses the highest quality stainless steel, unlike their competitors, crafting the 1-5/8" tuned primaries that merge into 2-1/2" collectors to create the smoothest flowing path. Every collector features Kooks' scavenging spike to ensure maximum flow. Every system is dyno- and race-tested to ensure the results are up to high-performance standards. Unleash the full potential of your Mustang's 4.6L 3V engine with the best long tube headers on the market.
