1-3/4 Full-Length Header 11-13 Mustang GT

The BBK PERFORMANCE 1-3/4 Full-Length Header 11-13 Mustang GT is a long-tube exhaust manifold engineered for Ford Coyote engine platforms in 2011–2023 Mustang GT models. Built for enthusiasts who demand maximum exhaust scavenging and horsepower gains, this header replaces restrictive factory manifolds and unlocks the breathing potential of modern Ford performance engines. The full-length tube design routes exhaust from all cylinders through equal-length primary pipes, eliminating turbulence and promoting efficient gas evacuation—a proven methodology used in high-performance and racing applications.

Constructed from steel and finished with titanium ceramic coating, the 1-3/4 inch primary tubes converge into a 2.75 inch collector, optimizing velocity and reducing backpressure across the RPM band. The titanium ceramic thermal barrier reduces underhood temperatures, protecting adjacent components and improving engine bay longevity during sustained high-performance driving. Gaskets and mounting hardware are included, simplifying installation on compatible platforms. The weighty 38.7 lbs specification reflects robust construction quality—cast or welded steel components designed to withstand repeated thermal cycling and vibration inherent to forced-induction and naturally aspirated power builds.

This header delivers measurable gains for Mustang GT owners pursuing bolt-on performance upgrades, track duty, or street applications demanding reliable flow enhancement. Compatibility is limited to 2011–2023 Ford Mustang GT models equipped with the Ford Coyote engine family; fitment on earlier or turbocharged variants requires verification. Installation requires basic mechanical skill and appropriate torque tools; professional installation is recommended for optimal sealing and longevity. Pair this header with a catback exhaust system and tune-up service to maximize dyno-proven power delivery.
