Improve the sound and performance on your Chevy Silverado and GMC Sierra with premium headers from Stainless Works. American-Made and designed for the 2019+ Chevy Silverado and GMC Sierra 5.3L, these headers feature 1-7/8" primary tubes that are CNC mandrel bent to increase air flow, and engineered to create power. These headers come with 3" slip-fit collectors, as well as high-flow catalytic converters that flow into 3" lead pipes, merging into a Y-pipe to allow an easy connection to your factory exhaust. Built from corrosion resistant 304 stainless steel, our headers are TIG welded for strength and durability at our state-of-the-art facility in Streetsboro, Ohio. We stand by our products with a lifetime warranty on materials and craftsmanship, and as always, our products are proudly made in the USA.
