Let your 6.2-litre V8 do more of the talking
Upgrade the front exhaust on your 6.2-litre GM truck with Kooks long tube headers and a matching GREEN catted Y-pipe. The kit pairs 1-7/8" headers with a 3" Y-pipe and a 3-1/2" OEM rear outlet, so you can improve the front system while keeping the rear exhaust you enjoy.
SKU: 2863H430
A kit matched to the 6.2
The 1-7/8" primaries lead into 3" collectors and the supplied GREEN Y-pipe. The 3-1/2" rear interface is part of this 6.2-litre configuration; it is different from the 2-3/4" outlet used on the equivalent 5.3 kit. That makes the engine choice relevant to the complete exhaust, not just the headers.
Ready for your supercharged build
GREEN cats suit both naturally aspirated and forced-induction engines, making this the appropriate choice if your 6.2-litre build includes a supercharger. The headers and Y-pipe arrive as a matched front system, with the OEM rear connection for your existing exhaust.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
