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

The BBK PERFORMANCE 1-3/4 Full-Length Header for 2011-2013 Mustang GT is designed for serious enthusiasts seeking maximum exhaust scavenging and horsepower gains on fifth-generation platform muscle cars. This full-length header replaces restrictive factory exhaust manifolds with tuned-length primary tubes, allowing exhaust gases to exit more efficiently and enabling the engine to breathe harder at higher RPMs.

Built for bolt-on installation without cutting or welding, this header serves as the foundation of any serious Mustang GT exhaust build and is a proven upgrade for both street and track applications. The 1-3/4 inch primary tube diameter is optimal for naturally aspirated 5.0L Coyote engines, balancing scavenging efficiency across the entire RPM range without sacrificing low-end torque. The factory coated finish provides thermal protection and corrosion resistance, reducing underhood heat while preserving durability in harsh driving conditions.

Owners upgrading to this BBK header typically pair it with a cat-back exhaust system and tune to unlock significant horsepower gains and improved throttle response. Mandrel-bent construction ensures smooth, unrestricted flow paths throughout each primary tube, eliminating the turbulent flow and dead spots inherent in cast manifolds. The full-length design routes all eight cylinders through a proper collector, synchronizing exhaust pulses for superior scavenging pulse effect compared to short-tube or step-tube alternatives.
