Cat-Back Exhaust System (5F1100) - 2017-2020 F-150 EcoBoost
Enhance the look and sound of your EcoBoost F-150 with the COBB Cat-Back Exhaust. Designed to fit SuperCrew with a 5.5' bed or SuperCab with a 6.5' bed, this system is constructed from high-quality mandrel-bent 304 stainless steel for maximum exhaust flow and long-lasting durability. It features an integrated flex section to reduce stress, a triple-chambered muffler that delivers a crisp exhaust note without unwanted cabin drone, and dual 4" polished tips featuring the COBB logo.
As a direct factory replacement that requires no tuning, it connects easily to the factory downpipe using an OEM-style 2-bolt flange, while the remaining sections use heavy-duty cast 3" 2-bolt flanges and multi-layer steel gaskets for a leak-free seal.
