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 when equipped with the non-valved factory exhaust. Built to unlock the aggressive character of Ford’s iconic pony car, this axle-back exhaust system pairs the legendary Outlaw-series mufflers with mandrel-bent tubing and polished tips for a genuine bolt-on transformation in both sound and style.
If you’ve been searching to shop for exhaust upgrades that deliver real, measured results, this performance exhaust makes its case on the dyno. Flowmaster recorded maximum gains of up to 8 horsepower and 7 lb-ft of torque at the rear wheels, thanks to a 3.00-inch mandrel-bent 409 stainless steel exhaust pipe design that maximizes flow while standing up to the elements.
Sound & Performance
At the heart of the kit are the Outlaw-series mufflers, tuned to produce an aggressive to moderate exhaust tone that gives your Mustang serious presence without sacrificing daily drivability. The 16.75-inch mufflers feature a center inlet and center outlet with a 3.00-inch outlet diameter, and each Black-finished muffler is included in the kit ready to install.
Style & Build Quality
Dual 4.00-inch polished stainless steel tips finish the system with a custom look worthy of this iconic vehicle, complete with an embossed tip logo. The silver painted pipe finish and durable 409 stainless construction are designed to deliver lasting performance whether your Mustang is a coupe or convertible.
Easy, Bolt-On Installation
This is a true axle-back exhaust system that uses the factory hangers and factory mounting locations, and all necessary hardware is included. That means a straightforward installation with no cutting or fabrication required, letting you upgrade your car exhaust and get back on the road quickly.
