The Kooks 2250H630 2-inch x 3-inch long tube headers and GREEN catted connection pipes kit delivers the ultimate bolt-on exhaust upgrade for 2010–2015 Camaro SS (LS3/L99) and ZL1 (LSA supercharged) models with the 6.2L V8, replacing factory manifolds to unlock dyno-proven gains of 70–90 rear-wheel horsepower and 80–100 lb-ft of torque through equal-length primaries, merged collectors, and high-flow 3-inch GREEN catted pipes that bolt directly to the OEM mid-pipe for seamless integration and unrestricted flow from idle to redline.
