2017-2020 Ford F-150 EcoBoost Cat-Back Exhaust by Cobb Tuning

The COBB Cat-Back Exhaust for the EcoBoost F-150 is constructed of quality 304 stainless steel tubing. Mandrel bends ensure maximum flow throughout the entire system. An integrated flex section provides a small amount of compliance during installation and reduces stress on components once installed. The triple-chambered muffler with 3" inlet/outlets keeps the exhaust note crisp and prevents unwanted drone. The three sections are joined together using cast 3" 2-bolt flanges and multi-layer steel gaskets for a leak-free assembly. Connecting to the factory downpipe assembly is a breeze with an OEM style 2-bolt flange.

The COBB F-150 Cat-Back Exhaust brings classic styling and high quality construction to your F-150's exhaust. As a direct factory replacement with no tuning required, it's a simple way to improve the looks and exhaust note of your EcoBoost F-150.
