JBA 04-07 F150 5.4L 409 Stainless Steel 1-5/8" Cat4ward Headers
JBA Cat4ward Headers are the perfect upgrade for today's emissions controlled cars, trucks and SUVs. Engineered with heavy duty features and patented technology, these headers deliver serious performance gains without compromising your vehicle's emissions equipment. The bolting on a set of precision made JBA Cat4ward Headers increases your engine's breathing ability and overall efficiency. The result is a significant increase in horsepower and torque throughout the RPM range and a reduction in the under-hood temperature. You will also improve the throttle response, and in some cases, your vehicless fuel economy. (Note: Due to variation in stock motor mounts some material may have to be removed for clearance.)
