Description
Overview
The Flowmaster Outlaw Cat-back Exhaust System is built for the hard-core enthusiast who wants their 2011-2012 Mustang GT to sound as serious as it drives. Engineered specifically for the 5.0L engine, this complete cat-back system pairs Flowmaster’s race-proven Outlaw Series mufflers with mandrel-bent stainless steel tubing to unleash a very aggressive exterior tone along with an aggressive interior sound. If you want your 5.0L to announce its presence at every start-up and pull, the Outlaw Series delivers.
At the heart of the system is the exclusive Scavenger Series X-pipe, designed to maximize power while producing the deep, distinctive tone Flowmaster is known for. Dual 3.00-inch mandrel-bent stainless steel tubing keeps flow smooth and unrestricted from the cat-back rearward, and a pair of Outlaw mufflers finishes the package with the loud, uncompromising character this series is built around.
Key Benefits
Every detail is aimed at real-world performance and easy ownership. The large 3.00-inch mandrel-bent tailpipes mount to the factory hanger locations, so the system tucks up cleanly without cutting or fabrication, and they’re capped with polished 4.00-inch 304 stainless steel tips for a finished, aggressive look under the rear bumper. The dual tailpipe layout completes the muscular presentation the Mustang GT deserves.

Complete Kit & Easy Installation
This is a complete cat-back package that includes the Outlaw mufflers, all necessary parts, mounting hardware, and detailed instructions so you can handle the install at home.

The system carries a 3.00-inch inlet diameter and comes finished in Silver with an aggressive sound profile that defines the Outlaw name.
