Description
Overview
The Flowmaster Outlaw cat-back exhaust system is built to transform the sound and flow of your 2021-2026 Ford F-150 equipped with the 2.7L, 3.5L, or 5.0L engine. Engineered as a complete exhaust system kit, it pairs an aggressive Outlaw-series muffler with mandrel-bent tubing to deliver a bolder tone and improved breathing over the restrictive factory setup. If you have been searching to shop for exhaust upgrades that combine real performance with a custom look, this catback exhaust is a direct, purpose-built answer for your F-150.
Flowmaster’s Outlaw series is known for an aggressive-to-moderate sound level, giving your truck a commanding presence without overwhelming the cabin. Backed by Flowmaster’s Lifetime Limited Warranty, this performance exhaust is designed to look, sound, and last the part.
Key Benefits
Constructed from durable 409 stainless steel, the tubing steps from a 3.00-inch inlet down to dual 2.50-inch tail pipes, all mandrel bent to maintain smooth, unrestricted flow. Max dyno gains are rated at 20 hp and 23 lb-ft at the rear wheels, so this isn’t just about sound — it’s a genuine power adder. Dual 4.00-inch black ceramic-coated tips with an embossed logo finish the setup with a clean, aggressive appearance out back.
