Coated Headers - SBF Tri-Y

The Coated Headers - SBF Tri-Y by Doug's Headers is designed specifically for small-block Ford engines that prioritize maximum exhaust scavenging and effective heat management. These headers strike a perfect balance between performance enhancement and durability, making them ideal for street and weekend builds where both power and longevity are essential.

The tri-Y configuration merges three separate primaries into a single collector, optimizing exhaust pulse timing and reducing backpressure. Doug's Headers applies a protective coating to these headers, which resists oxidation and minimizes underhood heat radiation, thereby extending the lifespan of the headers and surrounding components. The headers are engineered with mandrel-bent, tuned-length primaries to ensure consistent wall thickness and superior scavenging compared to stamped alternatives.

These coated headers are suitable for naturally aspirated small-block Ford engines, including the 5.0L, 302, and 351W platforms commonly found in Fox-body Mustangs, F-series trucks, and street rods. Installation requires the removal of factory cast manifolds and exhaust piping, and most builds will benefit from a mild tune and adjustments to carburetors or EFI to maximize performance.
