JBA 02-13 GM Truck 4.8L/5.3L LS Silver Ctd Cat4Ward Header

When you're looking to get more out of your GM truck's engine, starting with the exhaust is a smart move. This JBA Cat4Ward header set is designed to replace your restrictive factory exhaust manifolds, helping your 4.8L or 5.3L LS engine breathe easier. You'll get the headers themselves, which are made from durable stainless steel tubing, along with a proprietary JBA Firecone collector designed to maximize power and torque gains where you need them most – in the everyday driving RPM range. This kit also includes factory-style emission connections and high-quality hardware, so you can expect a professional, no-leak installation.

The construction here is solid. The tubing is mandrel-bent stainless steel, which means it maintains its diameter through the bends for consistent flow. The flanges are a beefy 3/8" thick with oversized exhaust ports, ensuring a good seal and accommodating the larger tube diameter. JBA also uses extra-thick collector domes, which adds to the overall durability. These headers are built to handle the demands of daily driving, towing, and even some spirited use, resisting corrosion and heat over time.

This header set fits a wide range of GM trucks and SUVs from 2002 through 2019, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe. It's a significant upgrade over stock manifolds, offering improved engine performance and a more satisfying exhaust note. Make sure to refer to the manufacturer's installation instructions for specific details on mounting and any other components you might need for your particular application.
