Kooks 1-3/4" Stainless Headers & Catted Y-Pipe Kit 2011-2014 F150 Raptor 6.2L 4V.

Kooks 1-3/4" x 3" Long Tube Headers & GREEN Catted Y-Pipe for 2010–2014 Ford F-150 SVT Raptor 5.4L 3V

The Kooks 1352H220 1-3/4-inch long tube headers and GREEN catted Y-pipe kit provides the complete bolt-on exhaust upgrade for 2010–2014 Ford F-150 SVT Raptor trucks with the 5.4L 3V Triton V8, replacing factory manifolds to deliver dyno-proven gains of 40–55 rear-wheel horsepower and 35–50 lb-ft of torque through equal-length primaries, merged collectors, and a high-flow 3-inch to OEM outlet GREEN catted Y-pipe that connects directly to the stock mid-section for unrestricted exhaust flow from low-end torque to high-RPM pulls.

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 up to 650 HP while maintaining 49-state emissions compliance and improving throttle response for quicker acceleration during towing up to 8,100 lbs or desert running. The precision design preserves ground clearance and heat management for off-road capable trucks without sacrificing the deep V8 rumble that enhances cabin experience.

For Raptor owners seeking immediate power and torque improvements with durable, emissions-legal construction, the 1352H220 kit unlocks the 5.4L 3V's full potential for trails, dunes, or performance driving.
