These are performance exhaust components designed specifically for the Ford Mustang manufactured from 1979 to 1993, often referred to as the “Fox body” generation. These aftermarket parts replace the factory exhaust manifolds and are characterized by their extended primary tubes which extend further down the chassis before converging into a collector.
Their installation can significantly improve engine performance by enhancing exhaust gas flow, leading to increased horsepower and torque. The design promotes scavenging effects, which aids in cylinder clearing and improves combustion efficiency. Originally designed for racing and high-performance applications, they have become a popular upgrade for enthusiasts looking to optimize the performance of these classic vehicles.
