JBA 14-20 GM Truck 4.3L V6 1-5/8in Primary Raw 409SS Cat4Ward Header

Starting with 3/8-inch thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your 2014-2020 Chevrolet Silverado 1500 or GMC Sierra 1500. They are a significant upgrade over the restrictive stock exhaust manifolds, designed to help your 4.3L V6 engine breathe easier and unlock more power and efficiency.

Constructed from durable 409 stainless steel tubing, these headers are made to last through daily driving, towing, and whatever else you throw at them. JBA's proprietary Firecone collector design is a key feature, using race-proven technology to maximize power and torque gains where you'll notice them most – in the everyday RPM range. The mandrel-bent tubing ensures consistent exhaust flow, further contributing to improved performance. Extra thick collector domes add to the overall robustness of the assembly.

Installation is made more straightforward with factory-style emission connections included, and high-quality hardware is provided to help ensure a professional, no-leak seal. These headers are a solid choice for improving the performance and sound of your truck's exhaust system.
