Description
Performance Exhaust Upgrade. The Flowtech 1-5/8-Inch Shorty Headers, finished in black paint, replace restrictive factory exhaust manifolds to enhance exhaust flow, resulting in improved engine performance and throttle response. These headers meet emissions compliance requirements while maximizing power output and driving experience.
Construction and Appearance. Made from heavy duty 16-gauge mild steel with mandrel-bent 1-5/8-inch primary tubes, these headers ensure smooth airflow and long-lasting durability. The black high heat resistant paint finish protects against corrosion and provides a sleek appearance that enhances the engine bay.
Installation. Installation is straightforward and requires no cutting or welding, as the OE style 2-1/2-inch ball and socket collector fits directly to the factory exhaust head pipe. Basic mechanical skills are sufficient to complete the installation process.
Application. Designed to fit 2002-2013 Chevrolet Silverado 1500 models equipped with 4.8L or 5.3L V8 engines, these headers integrate seamlessly with factory components and emissions systems.
