Built for F-150 owners who want maximum exhaust flow and an aggressive sound note without compromise, the MBRP S5209409 cat-back delivers a 4-inch T409 stainless steel system sized for the 2.7L EcoBoost, 3.5L EcoBoost, and 5.0L Coyote alike across 2021-2026 model years.
Race-version sizing, street-truck fitment. The 4-inch diameter tubing runs from the factory connection point back through a straight-through design that prioritizes exhaust scavenging and flow over restriction. The race designation means no muffler baffling sacrifices flow for noise reduction, so the exhaust note reflects what the engine actually produces.
T409 stainless construction throughout. T409 stainless steel resists corrosion from road salt, condensation, and heat cycling, keeping the system looking and functioning clean through daily driving and work-truck conditions. Every component in the system carries the same material spec, so there are no weak points where mild steel would corrode first.
Broad trim compatibility across the lineup. The S5209409 fits XL, XLT, STX, Lariat, King Ranch, Platinum, Limited, and SSV configurations for 2021-2026, covering virtually the entire F-150 range on all three available engine options.
