Product Description

The Stainless Works FTR25HCAT is a direct-fit long tube header kit engineered exclusively for the 2023-2025 Ford F-150 Raptor R with the 5.2L supercharged V8 - this kit does not fit the standard Raptor. Featuring 2" CNC mandrel-bent primary tubes flowing into 3" lead pipes, the system dramatically reduces exhaust backpressure compared to the factory manifolds, delivering significant gains in horsepower and torque right where the supercharged V8 thrives. EPA-compliant high-flow catalytic converters are included to maintain emissions compliance while maximizing flow, and a purpose-built driver side elbow ensures precise fitment within the Raptor R's tight engine bay.

The entire kit is built from premium 304 stainless steel and fully TIG welded at Stainless Works' Streetsboro, Ohio facility, then finished with a natural mill look that complements the underhood aesthetic. Installation is a direct bolt-on with no cutting required, connecting seamlessly to either the factory exhaust or a Stainless Works catback system for a complete front-to-back performance upgrade. Backed by Stainless Works' Limited Lifetime Warranty on materials and craftsmanship, and proudly made in the USA.
