Kooks 1-7/8" x 3 Header & Green Catted X-Pipe Kit 14-17 Chevrolet SS, LS3 / 6.2L

Maximum Flow, Full Emissions Compliance: Long Tube Power Without the Compromise

The Kooks 1-7/8-inch long tube headers and GREEN catted X-pipe kit delivers the complete bolt-on exhaust upgrade for the 2014 and 2017 Chevrolet SS sedan with the 6.2L LS3 V8, replacing factory manifolds to unlock dyno-proven gains of 50 and 65 rear-wheel horsepower and 45 and 60 lb-ft of torque through equal-length primaries, merged collectors, and a high-flow 3-inch GREEN catted X-pipe that connects directly to the OEM mid-pipe for seamless integration and unrestricted flow from idle to redline.

Handcrafted from T304 aircraft-quality stainless steel with 3/8-inch laser-cut flanges, full TIG welds, and 300-cell metallic substrate GREEN catalytic converters, this system supports over 800 HP while remaining 49-state emissions compliant and preserving the SS’s refined dual-mode exhaust function for quiet cruising or wide-open track roar. The precision design maintains ground clearance and heat management for daily-driven performance sedans.

For Chevrolet SS owners who demand track-winning performance with street-legal reliability, the 2510H430 kit is the championship-proven, complete bolt-on solution trusted by LS enthusiasts worldwide.
