Flowmaster introduces our Outlaw stainless steel cat-back exhaust system for the 2021-2026 Ford F-150 RCSB trucks with the 2.7, and 5.0-liter engines. This system uses an Outlaw series muffler for an aggressive to moderate sound level and increased performance. 3.00-inch to dual 2.50-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system uses dual 4.00-inch black ceramic-coated tips for a custom look. Max dyno gains of 20 hp and 23 lb-ft at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
