The Kooks 1-7/8-inch long tube headers and GREEN catted connection kit delivers the complete bolt-on exhaust upgrade for 2006–2023 Chrysler 300C, Dodge Charger, Challenger, and Magnum models with the 6.1L SRT8 or 6.4L 392 HEMI V8, replacing factory manifolds to unlock dyno-proven gains of 45–60 rear-wheel horsepower and 40–55 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.
