Product Description

The Stainless Works FT18HCAT headers are engineered for 2015-2023 Ford F-150 trucks equipped with the 5.0 L Coyote V8. Featuring 17/8" mandrel-bent primaries and a 3" stainless steel X-pipe with integrated high-flow catalytic converters, they deliver increased exhaust flow, power gains, and a refined, deeper tone.

Constructed entirely in the USA from 304 stainless steel and backed by a lifetime warranty, this header kit bolts directly into stock exhaust paths and is designed for use with Stainless Works Performance-Connect exhaust systems. The headers offer improved throttle response and performance while maintaining connection compatibility with OEM and aftermarket components outside California emissions zones.
