Product Details
Starting with the 3/8-inch 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 makes them a solid upgrade for trucks used for daily driving, towing, or even racing.
Constructed from durable stainless steel, these headers are made to last. The tubing is mandrel bent for smooth airflow, and JBA's proprietary Firecone collector design uses proven race technology to help maximize power and torque gains in the RPM range where you'll likely be driving most often. The extra thick collector domes add to their robust construction. These headers also include factory-style emission connections and high-quality hardware, aiming for a professional installation that won't leak.
This header set fits a range of GM trucks from 1999 to 2002, including popular models like the Chevrolet Silverado 1500 and GMC Sierra 2500. They are specifically designed for 6.0L LS engines without A.I.R. but with EGR. If you're looking to free up some power and improve the breathing of your truck's engine, these headers are a well-built option.
