MBRP ARMOR BLK 3-Inch Cat-Back Exhaust for 2021-2026 F-150 - S5277BLK

The MBRP S5277BLK ARMOR BLK 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 black-coated aluminized steel with smooth mandrel-bent tubing, this system includes a muffler and features MBRP's Street Profile for a deeper exhaust note that is a bit louder than stock. The single side exit with dual 4.5-inch black tips provides a modern, stealthy appearance while retaining a classic side-exit layout.

The included dual-wall, angle-cut tips are constructed from T304 stainless steel and finished with a specialized high-heat black powder coating. 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 on testing with the 5.0L engine. The system uses a bolt-on installation and is intended for dry-condition use. PowerBoost, Tremor, and Raptor applications are excluded.
