The MBRP S5277AL ARMOR Lite 3-Inch Cat-Back Exhaust is designed for select 2021-2026 Ford F-150 trucks equipped with the 2.7L EcoBoost, 3.5L EcoBoost, or 5.0L gasoline engine. Constructed from heavy-gauge aluminized steel with smooth mandrel-bent tubing, this system includes a muffler and polished dual-wall exhaust tips. MBRP's Street Profile delivers a deeper exhaust note that is a bit louder than stock, while the single side exit with dual 4.5-inch tips gives the truck a modern, polished appearance.
MBRP reports gains of up to 11 horsepower and 8 ft-lbs of torque, along with up to a 28% increase in exhaust flow, based specifically on testing with the 5.0L engine. The system uses a bolt-on installation and is part of the ARMOR Lite series for dry-condition use. PowerBoost, Tremor, and Raptor applications are excluded.
