Description
Overview
The Flowmaster Outlaw Axle-back Exhaust System is engineered to unleash the true voice of your Ford Mustang GT. Built specifically for the 2018-2023 Mustang GT coupe and convertible equipped with the 5.0L engine, this bolt-on kit pairs proven Flowmaster acoustics with a purposeful, aggressive look. Constructed from 3.00-inch mandrel-bent 409S stainless steel tubing, the system flows into a pair of race-proven Outlaw mufflers to deliver a bold exterior tone with a noticeable interior sound level that lets you know your Pony means business.
Sound and Performance
At the heart of this system are the Outlaw Series mufflers, tuned for an aggressive sound character that stands out on the street and at the strip. The 3.00-inch tailpipes exit through the factory cutouts in the rear valance and are capped with quad 4.00-inch polished stainless steel tips featuring an embossed tip logo, giving your Mustang a finished, purposeful appearance that matches its attitude. This axle-back configuration retains the factory resonator mid-pipe, preserving a factory-integrated fitment while adding serious presence.
