Product Description

The MBRP S5277304 is an Armor Pro cat-back exhaust system engineered for the 2021-2026 Ford F-150 equipped with the 2.7L EcoBoost, 3.5L EcoBoost, or 5.0L V8 engine. Built entirely from T304 stainless steel with smooth mandrel-bent 3-inch tubing, this system is designed to maximize exhaust flow and provide long-term durability in all conditions - including road salt, snow, mud, and off-road use. Street Profile sound tuning gives the F-150 a noticeably deeper, more assertive exhaust character under acceleration while remaining composed at highway speeds, striking the right balance between performance presence and daily drivability.

Dyno-proven on MBRP's in-house chassis dynamometer, the S5277304 delivers up to 11 horsepower and 8 ft-lbs of torque on the 5.0L platform, along with a 28% improvement in exhaust flow over the factory system. The single side exit routes exhaust to a polished T304 stainless steel tip at the rear bumper for a clean, understated visual upgrade. Installation is fully bolt-on using factory OEM hangers - no cutting or welding required. This system is not compatible with the F-150 PowerBoost Hybrid or Raptor. Backed by MBRP's Lifetime Warranty.
