Description
Unleash the full character of your 2015–2017 Ford Mustang GT 5.0L V8 Fastback with this 3.0-inch Cat-Back Exhaust System, featuring a dual rear exit and twin 4.0-inch polished Pro-Series tips. Designed for performance-driven Mustang enthusiasts, this system is available in Xtreme or Sport sound levels, allowing you to tailor exhaust volume and aggressiveness to your build.
Built from 3.0-inch mandrel-bent tubing, this Cat-Back system significantly improves exhaust flow while reducing overall system weight. The included XX-Pipe enhances exhaust scavenging and produces a sharper, more aggressive tone, while the axle-back section determines final sound character. The dual-wall, slash-cut polished tips deliver a bold, high-performance appearance that perfectly complements quad-tip rear styling.
⚠️ Fitment Note: This system fits Premium Package Mustangs ONLY and requires a Roush Quad Tip or similar aftermarket rear valance modification to accommodate the twin-tip configuration.
