JBA 14-19 GM Truck 5.3L/6.2L DFI 1-5/8in Primary Raw 409SS Cat4Ward Header

Starting with 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your GM truck. They are designed to significantly reduce exhaust restriction compared to the factory manifolds, which can lead to improved engine power and efficiency. This is a popular upgrade for trucks equipped with the 5.3L or 6.2L engines, including models like the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and Chevrolet Tahoe.

Constructed from durable 409 stainless steel, these headers are made to withstand daily driving, towing, and even racing conditions. JBA's proprietary Firecone collector design is a key feature, utilizing race-proven technology to maximize power and torque gains in the RPM range where you typically drive. The tubing is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. The extra thick collector domes add to the overall robustness of the header assembly.

Installation is made more straightforward with the inclusion of factory-style emission connections, allowing you to retain your emissions equipment. High-quality hardware is also included to help ensure a professional, no-leak installation. While these are a significant performance upgrade, remember to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any other components you might need for your exhaust system project.
