The Flowmaster Flow FX Cat-Back Exhaust System delivers a powerful blend of performance, tone, and premium styling for the 2020–2026 Ford Explorer ST and Lincoln Aviator equipped with the 3.0-liter twin-turbo EcoBoost engine. Built from mandrel-bent 3.00-inch 409 stainless steel, this system improves exhaust flow for increased horsepower and torque while maintaining long-term durability.

A Flow FX muffler with a built-in X-pipe merge enhances exhaust scavenging and produces an aggressive-to-moderate European-inspired sound. Unique Helmholtz-style resonators help reduce interior drone for a refined driving experience. The system exits through dual 3.50-inch double-wall black ceramic-coated stainless steel tips that deliver a custom high-end appearance.

Designed for easy installation, this system uses all factory hanger locations and includes all necessary hardware. Dyno testing has shown maximum gains of up to 20 horsepower and 25 lb-ft of torque at the wheels. Backed by Flowmaster's Lifetime Limited Warranty, this cat-back system is an ideal upgrade for drivers seeking sound, performance, and style.
