Unleash the full potential of your Mustang's 5.0L 4V engine with the best long tube headers on the market. Kook’s long tubes are made from aircraft quality T304 stainless steel. Kooks only uses the highest quality stainless steel unlike their competitors. 1-7/8" tuned primaries merge into 3" collectors to create the smoothest flowing path.

Each Kooks exhaust system is designed specifically for the engine and vehicle it is built for. Kooks utilizes the firing order of the engine when designing their exhaust tubes. Every system is dyno and race tested to ensure the results are up to Kooks' expectations. This means Kooks can guarantee their exhaust makes the most horsepower and torque in the industry.

Each port is hand ground to make sure they are perfectly smooth so there is no exhaust constriction. Kooks systems are bolt-in and never require any cutting or welding. All necessary hardware is included with these headers.
