Product Description

The Kooks 1372H430 long-tube header and connection-pipe kit is a premium performance upgrade crafted for the 2022-2025 Ford F-150 Raptor R equipped with the 5.2 L supercharged Predator V8. The 1-7/8" stainless-steel primaries paired with 3" GREEN-catted connection pipes provide a smooth, high-flow exhaust path that reduces backpressure, improves scavenging and delivers substantial gains in mid-range torque - perfect for supercharged, high-output applications.

Constructed from aircraft-quality T304 stainless steel with mandrel-bent tubing and heavy-duty flanges, this kit is built to withstand high exhaust temperatures and stress under load. Installation is relatively straightforward: the kit is designed to bolt directly to factory mounting points and adapt to stock or aftermarket cat-back systems. Included hardware, gaskets, and O2-sensor extensions simplify the install process. With proper tuning, many users have reported gains of +50-70 horsepower and +60-80 lb-ft torque at the wheels - making this an ideal upgrade for street, off-road, or performance-oriented builds.

Because the 1372H430 system is purpose-built for the Raptor R's 5.2 L Predator V8 and exhaust routing, compatibility is limited to model years 2022 through 2025 of the F-150 Raptor R. This ensures fitment and performance integrity. Note: the kit is not CARB-legal - check local emissions and registration laws before purchasing.
