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

Purpose-Built 2 Inch Long Tube Headers for the 2023 through 2025 Ford F-150 Raptor R 5.2L Supercharged V8

The Kooks 1372H640 is a 2 inch by 3 inch long tube header and H.O. GREEN catted connection kit engineered specifically for the supercharged 5.2L Predator V8 in the Ford F-150 Raptor R, delivering maximum exhaust flow for the most powerful production Raptor ever built. Oversized 2 inch T304 stainless mandrel-bent primaries eliminate the flow restrictions that factory manifolds create under boost, feeding into 3 inch merged collectors with Kooks' patented scavenging spike inserts that continuously accelerate exhaust gases through the collector transition for improved scavenging across the supercharged powerband.

The included H.O. GREEN catted connection pipes use 4.5-inch bodied 300 CPSI high-output catalytic converters rated for forced induction applications, connecting directly to the OEM F-150 Raptor R catback system using standard flanges. Built from 3/8 inch laser-cut flanges with hand-ported Predator V8 cylinder head inlets, each 1372H640 is TIG-welded from 16-gauge aircraft-quality stainless steel and assembled to order at Kooks' USA facility. A professional ECU tune and O2 sensor spacers are recommended after installation for optimal performance on the Raptor R platform.

The 1372H640 fits all 2023, 2024, and 2025 Ford F-150 Raptor R models equipped with the 5.2L supercharged Predator V8. California residents: this product does not meet CARB standards and is not legal for street use in California.

Key Features

• 2 Inch Primary Tubes: Maximum diameter for the supercharged 5.2L Predator V8, mandrel-bent to eliminate flow restriction at every bend.
• H.O. GREEN Catted Connection Pipes: 4.5-inch bodied 300 CPSI high-output catalysts rated for forced induction, EPA-certified for 49-state use.
• Kooks Patented Scavenging Spike Collectors: 3 inch merged collectors with patented inserts accelerate exhaust gases and reduce turbulence for maximum scavenging.
• 3/8 Inch Laser-Cut Flanges: Hand-ported to match the Predator V8 cylinder head ports, preventing gasket blowout under boost.
• OEM Catback Compatible: Connection pipe outlets connect directly to the factory F-150 Raptor R catback without cutting or welding.
• T304 Aircraft-Quality Stainless Steel: 16-gauge construction with full TIG welds for long-term corrosion and heat resistance.

Frequently Asked Questions

Does the Kooks 1372H640 require a tune on the F-150 Raptor R?
A professional ECU tune is strongly recommended after installing the 1372H640. The supercharged 5.2L Predator V8 benefits significantly from recalibrated air/fuel ratios to take full advantage of the improved exhaust flow and avoid check engine lights.

Do I need O2 sensor spacers with the Kooks 1372H640?
Kooks recommends O2 sensor spacers, part number 9003A, for optimal O2 sensor operation on the Raptor R platform. These spacers help prevent false lean codes that can occur on supercharged applications with improved exhaust flow.

Does the Kooks 1372H640 connect to the factory Raptor R catback?
Yes. The H.O. GREEN connection pipe outlets are flanged to connect directly to the OEM F-150 Raptor R catback system without cutting or welding.

Is the Kooks 1372H640 legal in California?
No. The 1372H640 does not meet CARB standards and is not legal for street use in California or other CARB-regulated states. It is 49-state EPA compliant.

What years of F-150 Raptor R does the Kooks 1372H640 fit?
The 1372H640 fits 2023, 2024, and 2025 Ford F-150 Raptor R models with the 5.2L supercharged Predator V8.

How long is the lead time for the Kooks 1372H640?
The 1372H640 is built to order in the USA. Lead time is typically 4 to 6 weeks from order date.

What warranty does the Kooks 1372H640 carry?
Kooks provides a limited lifetime warranty on all stainless steel components and a 25,000-mile warranty on the H.O. GREEN catalytic converters.

Does the Kooks 1372H640 include all hardware for installation?
Yes. The kit includes Stage 8 locking header bolts, exhaust port gaskets, O2 sensor extension harnesses, clamps, and installation instructions. O2 sensor spacers are available separately as part number 9003A.

What power level are the H.O. GREEN catalysts in the 1372H640 rated for?
The 4.5-inch bodied 300 CPSI H.O. GREEN catalysts are rated for forced induction applications. They are engineered to withstand the heat cycles and flow volumes generated by the supercharged 5.2L Predator V8 platform.

Installation Instructions

Safely lift and support the F-150 Raptor R on a lift or jack stands. Disconnect the O2 sensor connectors and remove the factory exhaust manifolds from both cylinder banks of the 5.2L Predator V8. Clean all cylinder head flanges before positioning the Kooks 1372H640 headers using the included port gaskets and Stage 8 locking bolts, torquing to the specification shown in the included instruction sheet. Connect the H.O. GREEN connection pipes from the header collectors to the factory catback flanges and secure with the included hardware. Reconnect O2 sensors using the included extension harnesses. O2 sensor spacers, part number 9003A, are recommended for optimal O2 sensor operation on the Raptor R platform. A professional ECU tune is strongly recommended following installation to maximize performance on the supercharged 5.2L Predator. Professional installation is recommended for all forced induction header swaps.
