Description
Performance Exhaust Upgrade. The Flowtech 1-5/8-Inch Shorty Headers Black Painted are engineered to enhance exhaust flow and boost engine performance on compatible GM V-8 vehicles. They replace factory exhaust manifolds to increase throttle response and power output, making them an essential upgrade for enthusiasts seeking a more efficient exhaust system.
Construction and Appearance. Constructed from heavy duty 16-gauge mild steel, these headers feature mandrel-bent primary tubes for consistent diameter and smooth exhaust flow.

Finished with high heat resistant black paint, they provide a professional satin appearance that withstands harsh operating conditions.
Installation. These shorty headers install directly to the factory Y-pipe and emissions equipment without any cutting or welding. Installation requires basic mechanical skills and no drilling, allowing for a smooth upgrade process.
Application. Designed to fit 2002 to 2013 Chevrolet Silverado and GMC Sierra 1500 trucks equipped with 4.8L and 5.3L V-8 engines, ensuring a reliable, emissions-legal performance enhancement.
