The COBB F-150 Cat-Back Exhaust brings classic styling and high quality construction to your 2017, 2018, 2019, or 2020 Ecoboost F150's exhaust. Being a direct factory replacement with no tuning required, it's an easy way to enhance the looks and exhaust note of your Ecoboost F150. This COBB Catback Exhaust for the EcoBoost F-150 is constructed of quality 304 stainless steel tubing. Mandrel bends provide maximum flow throughout the entire system. An integrated flex section offers a small amount of compliance during installation and reduces stress on components once installed. The triple-chambered muffler has 3" inlet/outlets that keep the exhaust note crisp and stops 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 effortless with an OEM style 2-bolt flange.
