The MBRP S5281304 Armor Pro 3-inch cat-back exhaust system is designed to improve exhaust flow, efficiency, and power on the Ford F-150 while adding a refined, moderate exhaust tone. Its T304 stainless steel construction resists rust and corrosion for lasting durability, and smooth mandrel-bent tubing supports efficient flow. The system uses OEM hanger locations for a precise fit and features a dual passenger-side exit with two polished tips for a finished appearance. On 5.0L applications, testing showed gains of up to 6 horsepower and 9 lb-ft of torque. The moderate sound enhances the truck’s presence without overwhelming the cabin.
