Product Description

The MBRP S5231AL 3" Cat-Back Exhaust System is a genuine vehicle-specific performance upgrade engineered for 2018-2024 Ford Expedition SUVs equipped with the 3.5L EcoBoost V6 engine and a factory single exhaust setup. Designed with mandrel-bent aluminized steel tubing, this cat-back enhances exhaust flow and throttle response while delivering a deeper, street-oriented sound profile that's engaging yet manageable for daily drivers.

The direct bolt-on installation uses OEM hanger points and includes all required hardware for a straightforward install. Backed by a 3-year limited warranty, this exhaust system is ideal for Expedition owners seeking improved performance, better sound, and durable construction without major modifications.
