Stainless Works Long Tube Headers with Y-Pipe for 2015-2020 Chevrolet Suburban (Mill Finish). These long-tube, catted headers are built to improve exhaust flow and deliver a more aggressive tone while retaining factory connection points.

Designed for 5.3L Suburban applications, this Stainless Works kit uses CNC mandrel-bent 1-7/8" primary tubes that feed into 3" slip-fit collectors and 3" lead pipes which merge into a Y-pipe for easy connection to the stock exhaust. High-flow catalytic converters are integrated into the catted leads to meet emissions routing while improving flow. Components are fabricated from corrosion-resistant 304 stainless steel with TIG welds and a 3/8" thick flange for durability. Mill finish construction and American manufacturing in Streetsboro, Ohio back the product, which is offered with a lifetime warranty on materials and workmanship.
