Flowmaster American Thunder Cat-Back Exhaust System


Flowmaster introduces our new American Thunder stainless steel cat-back exhaust system for the 2021-2025 Ford F-150 with the 2.7L, 3.5L and 5.0L engines. This system uses a Super 40 series muffler for a deep powerful sound and increased performance. Maximum dyno gains of 11 HP and 10 LB.FT. at the rear wheels. Mandrel bent 409 stainless steel tubing is used for maximum exhaust flow and durability. The system has a 3.0-inch inlet pipe and dual 2.5-inch tailpipes with both side exit and rear exit options that allow you to customize the look of the kit. 3.5-inch polished stainless steel tips finish off the kit for a classic performance look. All of the necessary hardware is included and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
