Description
Maximize the performance and sound of your 6.6L gas-powered Chevy Silverado HD or GMC Sierra HD with the Stainless Works 2” Long Tube Header Kit. Precision-engineered for serious performance gains, this complete factory-connect system is designed to improve exhaust flow, unleash horsepower, and deliver a bold exhaust note while maintaining compatibility with your stock or upgraded cat-back system.
This header kit features large 2” diameter primaries that flow into a high-performance 3” collector with a built-in merge spike for optimized scavenging and torque. The kit includes high flow catalytic converters and offers your choice of a Y-pipe or X-pipe to complete the system for a seamless factory connection—making installation straightforward and eliminating the need for extensive fabrication.
Designed to connect directly to the OEM exhaust or any Stainless Works Legend or Redline cat-back systems, this kit can also be used to convert your truck into a true dual exhaust setup when paired with the corresponding Stainless Works cat-backs.
Crafted from 304 stainless steel and TIG welded in Stainless Works’ Ohio facility, these headers are built to last, delivering long-term durability and performance. Backed by a limited lifetime warranty, this is an American-made upgrade you can trust.
