The Corsa 21166BLK Sport Cat-Back Exhaust System is purpose-built for 2021-2025 Ford F-150 trucks equipped with the 3.5L EcoBoost engine and 145.4" wheelbase.

The single side exit layout with black PVD-coated dual 4.0" tips adds a refined yet assertive appearance to your truck's profile.

Installation is straightforward thanks to a direct bolt-on design that eliminates the need for cutting or welding. This cat-back exhaust improves exhaust flow and throttle response while offering long-lasting corrosion resistance and backing from Corsa's limited lifetime warranty, making it ideal for F-150 owners who want more engaging sound and performance without sacrificing daily comfort.
