Kooks Headers 2022+ Ford F-150 Raptor R 5.2L 4V. 2in Header and H.O. Green Catted Conn.

Kooks 2" x 3" Long-Tube Headers & OEM H.O. GREEN Catted Connection Kit for 2023+ Ford F-150 Raptor R 5.2L V8

The Kooks 1372H640 header and connection kit delivers a direct bolt-on exhaust upgrade for 2023+ Ford F-150 Raptor R models, replacing the restrictive factory manifolds with 2-inch long-tube primaries and high-output GREEN catted connections that free up over 50 rear-wheel horsepower and 40 lb-ft of torque while keeping emissions in check for street use.

Mandrel-bent from T304 aircraft-quality stainless steel, the equal-length tubes and merged collectors enhance exhaust scavenging across the supercharged 5.2L V8's broad powerband, providing sharper throttle response and a refined V8 growl without cabin drone during highway runs.

The 3-inch to OEM high-output GREEN catalytic connections integrate flawlessly with the factory mid-section, handling up to 850 HP from tunes or blower upgrades, and feature precision 3/8-inch laser-cut flanges to resist warping under repeated heat cycles. For Raptor R owners pushing the limits in desert runs, drag strips, or daily hauls, this kit offers the full drivetrain flow needed to extract the Godzilla engine's full potential without compromising drivability.
