Full-length exhaust headers that replace the factory manifolds on 2015-2020 F-150s with the 5.0L V8, bolting straight into the stock exhaust connection while keeping working catalytic converters so the check-engine light stays off.
why this one — A direct bolt-on 'Factory Connect' design with EPA-compliant high-flow cats makes this a street-friendly long-tube option for Gen 2-3 trucks.
Checked Stainless Works' own product page (stainlessworks.net/2015-20-f-150-5-0l-long-tube-header-kit-factory-connect) on 2026-07-26: NO numeric hp or torque figure. Page carries a "Dyno-Proven Power" banner and the phrase "maximum power" but publishes no measured result. Dyno wording without a number must not be read as a tested figure. Kit is described as including "EPA compliant" high-flow catalytic converters; no CARB EO number is published, so no California street-legal claim is made here.
