JBA 03-06 GM Truck 6.0L LS w/o EGR 1-5/8in Primary Silver Ctd Cat4Ward Header

Starting with the 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built for serious performance on your GM truck. They're designed to replace the restrictive stock exhaust manifolds, which can significantly increase your engine's power and efficiency. This particular header is made for 6.0L LS engines without EGR, fitting a wide range of popular trucks and SUVs like the Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Hummer H2 from the early to mid-2000s.

Constructed from durable stainless steel tubing, these headers are made to handle the demands of daily driving, towing, and even racing. JBA's proprietary Firecone collector design is a key feature, using proven race technology to maximize power and torque gains right where you need them most during normal driving. The tubing is mandrel-bent for smooth airflow, and the collector domes are extra thick for added longevity. You'll also find factory-style emission connections included, along with high-quality hardware, to help ensure a professional, leak-free installation.

When you're looking to get more out of your engine, these headers are a solid option. They're designed to fit right and work with your existing exhaust system, and the silver coating adds a layer of protection and a clean look. Make sure to check the fitment details to confirm compatibility with your specific vehicle.
