Description
Performance Exhaust Upgrade. The Flowtech 1-3/4-Inch Shorty Headers; Ceramic deliver improved exhaust flow and increase throttle response. Designed for high-performance applications, these headers enhance engine efficiency by replacing restrictive factory manifolds and are ideal for vehicles equipped with cold air intakes, cat-back exhausts, or tuners.
Construction and Appearance. Crafted from heavy-duty 16-gauge mild steel, these headers feature mandrel-bent tubes for optimal exhaust velocity and durability. The satin silver metallic ceramic coating acts as a thermal barrier, reducing underhood temperatures while providing a sleek, professional finish. The headers include TIG-welded, machined header flanges to ensure a leak-free and secure installation.
Installation. Installation is straightforward with factory-style flange connections requiring no cutting or welding. These headers fit directly onto the factory exhaust head pipe, making the process accessible without the need for drilling or additional modifications.
Application. These headers fit 2003-2013 Chevy and GMC 6.0L engines across Silverado, Sierra, Tahoe, and Yukon models, including both 2WD and 4WD configurations, providing broad compatibility with stock setups.
