Kooks 1-7/8" x 3" Long Tube Headers & GREEN Catted Connection Kit for 2009–2023 Chrysler 300C 5.7L HEMI RWD
The Kooks 3100H430 1-7/8-inch long tube headers and GREEN catted connection kit delivers the complete bolt-on exhaust upgrade for 2009–2023 Chrysler 300C models with the 5.7L 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.
Handcrafted from T304 aircraft-quality stainless steel with 3/8-inch laser-cut flanges, full TIG welds, and 400-cell metallic substrate GREEN catalytic converters, this system supports over 750 HP while remaining 49-state emissions compliant and preserving the 300C’s refined V8 soundtrack without drone. The precision design maintains factory ground clearance and heat shielding for daily-driven luxury performance sedans.
