6675S 4.6L Long Tube Exhaust Headers

The JBA 6675S is a performance-grade, full-length exhaust header system engineered for the 2005-2010 Ford Mustang GT models equipped with the 4.6L V8 engine. Constructed from durable stainless steel, these headers boast 1.75-inch diameter mandrel-bent primary tubes and 2.5-inch collector ports, designed to maximize horsepower and torque gains, particularly at higher RPMs. The headers feature extra-thick, 3/8-inch one-piece CNC laser-cut flanges for a secure and leak-free seal, and include O2 sensor provisions and patented JBA Firecone® merged collectors for optimal exhaust flow. It is important to note that these headers are for closed-course competition use only and are not street legal in all areas. Users must certify their intended use (competition, pre-emissions controlled vehicle, or replacement part under specific conditions) to comply with federal and state emissions laws. The product application is specifically for the 2005-2010 Ford Mustang GT with the 4.6L engine.
