The COBB Cat-Back Exhaust for the 20172020 Ford F-150 EcoBoost combines premium construction, smooth flow, and a refined exhaust note in a direct factory replacement system. Built entirely from 304 stainless steel, this exhaust system is engineered to resist corrosion while providing long-term durability.

Featuring 3-inch mandrel-bent tubing, the system maximizes airflow throughout, reducing restriction and unlocking a deeper, more aggressive tone. A triple-chambered muffler balances sound output, keeping the exhaust crisp while eliminating unwanted drone at cruising speeds.

Installation is made simple with cast stainless steel 3-inch 2-bolt flanges and multi-layer steel gaskets, ensuring a tight, leak-free seal. An integrated flex section adds compliance during install and reduces stress on connected components once in place. The system finishes off with dual 4-inch polished tips etched with the COBB logo, giving the rear of your F-150 a clean, performance-inspired look.

Compatible with SuperCrew models with 5.5′ bed and SuperCab models with 6.5′ bed, the COBB Cat-Back Exhaust connects seamlessly to the factory downpipe assembly using an OEM-style 2-bolt flange. No tuning is requiredjust bolt it on and enjoy a more refined exhaust note and upgraded styling.
