Kooks 1-7/8" x 3" Long Tube Headers & GREEN Catted Connection Pipes for 2016–2024 Chevrolet Camaro SS/ZL1 6.2L LT1/LT4

The Kooks 2261H630 1-7/8-inch long tube headers and GREEN catted connection pipes deliver the ultimate bolt-on exhaust upgrade for 2016–2024 Camaro SS and ZL1 models with the 6.2L LT1 or supercharged LT4 V8, replacing factory manifolds to unlock dyno-proven gains of 55–75 rear-wheel horsepower and 50–70 lb-ft of torque through equal-length primaries, merged collectors, and high-flow 3-inch GREEN catted pipes that bolt directly to the factory 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 1,000 HP while remaining 49-state emissions compliant and preserving the Camaro’s aggressive V8 soundtrack without drone. The precision design maintains factory ground clearance and heat shielding for daily-driven performance machines.
