JBA 5.0L Mustang 1-3/4" Shorty Headers (Silver Ceramic Coated)

JBA started with a clean sheet of paper when designing our 50 State Legal Headers for the NEW powerful 5.0L 4v Mustang. Extensive development and dyno time yielded huge gains in both torque and horsepower over the restrictive factory manifold. JBA's 50 State Legal - CARB approved Headers features a thick 3/8" one piece head flange leading into the heavy-wall 1-3/4" stainless steel primaries tubes and ends with the patented JBA Firecone® merge collector. Never worry about replacing the cracked manifolds and stay emissions legal for all 50 states. JBA 1685S series headers are the ONLY 50 State - CARB approved header on the market today for late model 2011-2014 Ford Mustangs. – CARB EO # D-57-27
