Description
High Performance Headers. The Flowtech 1-5/8-Inch Shorty Headers; Raw are designed to enhance exhaust flow and increase engine efficiency. They are engineered to improve throttle response and overall performance for late-model V8 engines. These headers are built to fit seamlessly onto your engine without modification, making them a valuable upgrade for enthusiasts seeking better power delivery.
Construction and Appearance. Crafted from mandrel-bent 409 stainless steel tubing, these headers provide consistent diameters for smooth exhaust flow. The heavy-duty 16-gauge tubing ensures durability and strength, while the raw natural finish offers a durable semi-gloss silver look that resists corrosion. Precision TIG welding and machined 3/8-inch flanges guarantee a tight, leak-free seal.
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. No drilling or advanced modifications are necessary, making this a relatively easy upgrade for experienced installers.
Application. This product fits the 2014-2015 V8 Chevrolet Silverado 1500 Sierra 1500 trucks, offering a precision fit for these models without exceptions.
