The Kooks 3103H640 2-inch x 3-inch long tube headers and H.O. GREEN catted connection kit unleashes the supercharged fury of 2015+ Dodge Charger and Challenger Hellcat models with the 6.2L HEMI V8, replacing factory manifolds to deliver dyno-proven gains of 60 and 80 rear-wheel horsepower and 70 and 90 lb-ft of torque through equal-length primaries, merged collectors, and high-flow 3-inch x 2-3/4-inch OEM outlet H.O. GREEN catted pipes that bolt directly to the factory exhaust for unrestricted flow under extreme boost pressures exceeding 15 PSI.
Handcrafted from T304 aircraft-quality stainless steel with 3/8-inch laser-cut flanges, full TIG welds, and 400-cell metallic substrate H.O. GREEN catalytic converters, this system supports over 1,000 HP while remaining 49-state emissions compliant and preserving the Hellcat's signature supercharged howl without drone during highway cruising or drag launches. The precision design maintains ground clearance and heat management for street-driven muscle cars without sacrificing the aggressive V8 soundtrack that dominates the quarter-mile.
For Hellcat owners who demand track-dominating performance with street-legal reliability, the 3103H640 kit is the championship-proven, complete bolt-on solution trusted by drag racers and enthusiasts worldwide.
