The Kooks Tubing Kit of 1-7/8" stainless steel headers and GREEN catted Y-pipe is designed for optimized flow on 2019–2024 6.2L Chevy and GMC trucks.
This complete exhaust upgrade includes precision-engineered long tube headers and a Y-pipe equipped with EPA-compliant GREEN catalytic converters. The 1-7/8" primaries and 3" collectors are built from mandrel-bent T304 stainless steel, providing reliable durability and enhanced exhaust scavenging. The included Y-pipe maintains compatibility with OEM exhaust outlets while integrating Kooks’ high-flow catalytic converters, offering reduced backpressure and emissions performance. This system is a direct-fit solution tailored specifically for 6.2L V8 engines on Silverado, Sierra, and related GM truck models, supporting naturally aspirated and tuned applications. Installation requires no permanent modification and retains emissions compliance in applicable states.
