1-3/4 Swap Headers SBF 351W 86-93 Mustang

The 1-3/4 Swap Headers SBF 351W 86-93 Mustang by BBK Performance is designed for third-generation Mustang owners looking to enhance exhaust flow and engine responsiveness specifically for the 351W Windsor engine platform. These headers provide a direct bolt-on solution that addresses factory restrictions, improving horsepower and throttle response in stock configurations.

With a primary tube diameter of 1-3/4 inches, these headers are optimized for the 351W's displacement and power band characteristics, enhancing scavenging while maintaining low-end torque. The mandrel-bent construction ensures smooth internal geometry, minimizing turbulence and exhaust reversion that are common with stock cast-iron manifolds. Additionally, the high-temperature ceramic coating resists rust and reflects heat, extending the service life of the headers.

Enthusiasts and mechanics working on naturally aspirated 351W builds, from mild street engines to those exceeding 400 horsepower, will experience significant gains in mid-range power and peak output. These headers are compatible with factory headers-back exhaust systems, making installation straightforward while ensuring compatibility with existing driveline components.
