Description
Overview
The Flowmaster Outlaw Axle-back Exhaust System is engineered specifically for the 2024-2026 Ford Mustang, fitting both the 5.0-liter GT and the 2.3-liter EcoBoost with the non-valved factory exhaust. Built to deliver an aggressive, unmistakable tone and real performance gains, this Outlaw-series exhaust system transforms the sound and rear-end look of your Mustang without the guesswork of a custom fabrication. Whether you’re shopping for exhaust upgrades for a coupe or a convertible, this kit is designed to fit both body styles right out of the box.
At the heart of this performance exhaust are the Outlaw-series mufflers, tuned to produce an aggressive to moderate exhaust tone that gives your Mustang a bold, purposeful voice. Flowmaster measured maximum dyno gains of up to 8 horsepower and 7 lb-ft of torque at the rear wheels, so this car exhaust delivers measurable output alongside its signature sound.
Key Benefits
Every exhaust pipe in this system is constructed from 3.00-inch mandrel-bent 409 stainless steel tubing to maximize exhaust flow and long-term durability. Mandrel bending keeps the piping diameter consistent through every bend, promoting smoother flow than crush-bent alternatives. The system is finished with dual 4.00-inch black ceramic-coated tips featuring an embossed logo, adding a clean, custom look to one of America’s most iconic vehicles.
