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

Starting with the 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle serious work. They're designed for a range of GM trucks from 2003 to 2006, including popular models like the Chevrolet Silverado 1500 and GMC Sierra 2500 HD, as well as the Cadillac Escalade and Hummer H2. These headers replace your restrictive stock exhaust manifolds, helping your 6.0L LS engine breathe better and make more power. You'll notice improved engine performance and efficiency, whether you're towing, daily driving, or hitting the trails.

The stainless steel construction means these headers are well-built to resist corrosion and endure the demands of daily use and heavier applications. JBA's unique Firecone collector design is a key part of how these headers achieve maximum power and torque gains in the RPM range you use most often. The tubing is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. Plus, they include factory-style emission connections and all the necessary hardware for a professional, leak-free installation, making the upgrade process smoother.

When you're looking to get more out of your GM truck's 6.0L LS engine, these JBA headers are a solid option. They are designed to fit without EGR, simplifying the installation for many applications. The kit comes with everything needed for a complete installation, so you can get back on the road with improved performance.
