Flowmaster 818168 Outlaw Cat-Back Exhaust System

Flowmaster introduces our Outlaw cat-back exhaust system for the 2021-2026 Ford F-150 with the 2.7, 3.5, or 5.0-liter engine and factory dual exit exhaust.

Dual 4.50-inch black ceramic coated stainless steel tips are used to add a custom look to the truck. All the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
