Product Description

The Kooks 1372H640 long-tube header and connection kit is a premium exhaust upgrade engineered specifically for 2022-2025 Ford F-150 Raptor and Raptor R models equipped with the 5.2 L 4-valve V8. With 2.00" mandrel-bent stainless primaries and high-flow 3.00" GREEN catted connection pipes, this kit is designed to significantly improve exhaust flow, reduce back-pressure, and enhance engine breathing - translating to better throttle response, stronger mid-range torque, and overall performance gains.

Manufactured from high-quality 304 stainless steel, the headers are built to withstand high exhaust temperatures and resist corrosion, ensuring durability even under off-road, heavy load, or aggressive driving conditions. Because the kit includes all necessary hardware, gaskets, and connection pipes, installation is straightforward with factory mounting points - making it viable for both enthusiast DIY installs and professional builds. The inclusion of GREEN catted connection pipes helps maintain better emissions compliance compared to cat-less headers (though local/emissions regulations must be checked before use).

This kit is ideal for owners who want to unlock the full potential of the F-150 Raptor/Raptor R's Predator V8 engine - whether for improved on-road performance, off-road torque delivery, or a more aggressive exhaust note. As with all high-flow header systems, a proper ECU tuning or recalibration is recommended after installation to optimize performance and avoid potential drivability issues.
