Flowtech 1-5/8-Inch Shorty Headers; Ceramic (02-13 4.8L, 5.3L Silverado 1500)

Description

Performance Exhaust Headers. The Flowtech 1-5/8-Inch Shorty Headers with ceramic coating provide enhanced exhaust flow and increased throttle response for the 4.8L and 5.3L engines. Designed to replace restrictive stock manifolds, they improve engine efficiency and overall performance for both enthusiast and professional use.

Construction and Appearance. Crafted from heavy-duty 16-gauge mild steel, these shorty headers feature mandrel-bent tubes that ensure smooth exhaust flow and durability. They are finished with a satin silver metallic ceramic thermal barrier coating that reduces underhood temperatures while offering a sleek, aggressive appearance.

Installation. Installation is straightforward, involving no cutting or welding as the headers connect directly to the factory exhaust using an OE style ball and socket collector. This allows for a simple installation process suitable for most skill levels.

Application. These headers are designed specifically for the 2002-2013 Chevrolet Silverado 1500 with 4.8L and 5.3L V8 engines, fitting both 2WD and 4WD configurations.
