MBRP Armor BLK 3" Cat-Back Exhaust, Single Side Dual Outlet (S5277BLK) - 2021-2026 Ford F-150
Give your Ford F-150 a bold upgrade in sound, flow, and attitude with the MBRP Armor BLK 3-inch Cat-Back Exhaust. Designed for 2.7L EcoBoost, 3.5L EcoBoost, and 5.0L F-150s, this system delivers a deeper, more authoritative tone paired with stealthy blacked-out styling.
Built from heavy-gauge aluminized steel and finished with a high-heat black coating, the S5277BLK offers excellent durability and a rugged appearance ideal for daily-driven trucks in dry climates. Smooth mandrel-bent tubing maximizes exhaust flow and efficiency, while testing on the 5.0L platform shows gains of up to 11 horsepower and 8 lb-ft of torque, along with a 28% increase in exhaust flow. A bolt-on design and black tips complete a clean, aggressive look with easy installation.
