Flowmaster Outlaw Axle-Back Exhaust For Mustang 5.0L (15-23) (817821)

The Flowmaster Outlaw axle-back exhaust system is a high-performance upgrade designed specifically for the 2018-2023 Ford Mustang GT coupe and convertible equipped with the 5.0L engine. Constructed from 3.00-inch mandrel-bent 409S stainless steel tubing, it directs exhaust flow into race-proven Outlaw mufflers to deliver an aggressive exterior sound with a noticeable interior tone. The system features 3.00-inch tailpipes that exit through the factory cutouts in the rear valance, complemented by quad 4.00-inch polished stainless steel tips for an aggressive visual appeal. It retains the factory resonator mid-pipe, allowing for a straightforward bolt-on installation. The design emphasizes durability, performance, and an unmistakable sound profile, with optional components available for further sound and power enhancements.

This axle-back system is compatible with 2018-2023 Ford Mustang GT models with the 5.0L engine, including both coupe and convertible variants. It is intended for vehicles without active exhaust valves and utilizes factory hanger locations for an easy, at-home installation that typically takes about an hour. The kit includes all necessary hardware and instructions, although installation requires cutting the factory mufflers from the mid-pipe. Ideal for street and performance driving, this system provides a significant sound upgrade and a bold appearance, making it suitable for enthusiasts seeking a race-inspired exhaust note and improved exhaust flow.
