Description
Performance Exhaust Upgrade. The Flowtech 1-5/8-Inch Shorty Headers in Black Painted finish enhance exhaust flow and improve throttle response for 2014-2015 Silverado 1500 5.3L and 6.2L LT engines. Designed for racing use, these headers optimize engine efficiency and increase power output for competitive applications.
Construction and Appearance. Crafted from mandrel-bent 409 stainless steel with heavy-duty 16-gauge tubing, these headers feature a durable black painted finish with a satin sheen. The TIG-welded, machined 3/8-inch flange ensures a leak-free seal, complemented by included premium aluminum header gaskets for added reliability.
Installation. Installation is straightforward and requires no cutting or welding, as the OE-style 2-1/2-inch ball-and-socket collector connects directly to the factory exhaust head pipe. Basic mechanical skills and standard automotive tools are necessary for a proper fit and secure mounting.
Application. Specifically built to fit 2014-2015 Chevrolet Silverado 1500 V8 LT engines, designed for both 2WD and 4WD configurations within this model year range.
