Product Description

The MBRP S5221AL 3" Resonator-Back Exhaust System is engineered as a vehicle-specific performance upgrade for 2021-2024 Ford F-150 trucks equipped with the 3.5L PowerBoost Hybrid V6 engine. Designed to replace the restrictive mid-section of the stock exhaust, this system uses mandrel-bent 3" aluminized steel tubing to improve exhaust flow, reduce back-pressure, and enhance throttle response. The resonator-back design strikes a balance between performance and daily drivability, delivering a deeper, richer street sound without becoming excessively loud.

Constructed from heavy-gauge aluminized steel in MBRP's Armor Lite series, the S5221AL offers reliable corrosion resistance and long-term performance. The single side exit with a polished 4" stainless steel tip adds clean rear styling while the direct bolt-on installation uses factory hanger points for a straightforward setup with included hardware. Backed by a 3-year limited manufacturer warranty, this exhaust system is ideal for F-150 PowerBoost owners seeking improved exhaust tone, better flow, and quality construction.
