Product Description

The MBRP S5248409 3" Cat-Back Exhaust System is engineered as a performance upgrade for 2011-2014 Ford F-150 trucks equipped with the 3.5L EcoBoost V6 engine. This exhaust replaces the restrictive factory system behind the catalytic converter with mandrel-bent 3" tubing to improve exhaust scavenging, throttle response, and overall airflow. With a street sound profile, it delivers a deeper and more engaging exhaust tone without excessive cabin drone, making it suitable for daily driving and spirited use.

Constructed from T409 stainless steel from MBRP's Armor Plus series, the S5248409 exhaust provides corrosion resistance and long-term durability. The single side exit and polished stainless steel tip enhance the rear-end appearance while offering a sleeker look compared to stock. Designed for a direct bolt-on installation using OEM hanger points with included hardware, this cat-back system is ideal for F-150 owners seeking improved performance, a refined exhaust note, and quality construction backed by a lifetime limited warranty.
