The Kooks Exhaust System combines 1-7/8-inch long tube headers and a GREEN catted Y-pipe engineered for 2014–2018 GM 6.2L truck applications.
This system is designed to enhance exhaust flow, reduce emissions, and maintain compatibility with factory-style components. The 304 stainless steel construction offers long-term durability while supporting high-output demands typical of performance-tuned trucks. The GREEN catalytic converters are EPA-compliant, making the assembly suitable for street-driven vehicles in regulated areas.
This setup is a direct-fit solution for Silverado, Sierra, and other GM 6.2L trucks that retain OEM-style configurations. Mandrel-bent tubing, TIG welds, and CNC-machined flanges contribute to reliable sealing, smooth flow, and resistance to thermal stress. The inclusion of oxygen sensor ports and factory-connection geometry ensures seamless integration with factory or aftermarket exhaust systems.
