Maximize exhaust flow and durability with these Stainless Works catted headers. Engineered to replace restrictive factory manifolds, these headers utilize 1-7/8-inch primary tubes that are CNC mandrel bent to eliminate internal restrictions and optimize exhaust gas velocity. The system features 3-inch slip-fit collectors and high-flow catalytic converters that transition into 3-inch lead pipes. These leads merge into an integrated X-pipe, designed for a direct connection to a Stainless Works exhaust system.

Constructed entirely from 304 stainless steel, these headers are TIG welded for superior joint strength and corrosion resistance. Manufactured in the USA, this kit provides a significant upgrade in material quality over OEM components while maintaining precise fitment for the 2019-2020 GM truck chassis.
