Description
Premium Performance Upgrade. The Flowtech 1-5/8-Inch Shorty Headers in Polished finish enhance exhaust flow and engine efficiency for 2014-2015 Silverado and Sierra 5.3L and 6.2L V8 engines. Designed to replace restrictive factory manifolds, these headers improve horsepower and torque by increasing exhaust velocity and reducing backpressure. They are ideal for enthusiasts seeking both power gains and reliability in their LT engine swaps.
Construction and Appearance. Crafted from mandrel-bent 409 stainless steel tubing with heavy-duty 16-gauge walls, these headers offer durability and consistent flow characteristics. The TIG-welded, machined 3/8-inch header flanges ensure a tight, leak-free seal. Finished in polished stainless steel, they provide a semi-gloss sheen that resists corrosion and adds a clean, professional look under the hood.
Installation. These shorty headers are designed for straightforward bolt-on installation requiring no cutting, welding, or drilling. They utilize OE-style ball and socket collectors to connect directly to the factory exhaust head pipes, reducing installation time and complexity.
Application. Specifically made to fit 2014-2015 Chevrolet Silverado 1500 and GMC Sierra 1500 models equipped with 5.3L and 6.2L V8 LT engines, these headers support both 2WD and 4WD configurations. They are not CARB-compliant, making them suitable for off-road or racing use only.
