Description
Upgrade your 2015–2017 Ford Mustang GT 5.0L V8 Fastback with this high-performance 3.0-inch Cat-Back Exhaust System, engineered with dual rear exit and twin 4.0-inch polished Pro-Series tips. Designed for Premium Package Mustangs, this system delivers aggressive styling and a configurable exhaust tone with your choice of Xtreme or Sport sound levels.
Featuring 3.0-inch mandrel-bent tubing, the system improves exhaust flow and reduces backpressure, allowing the Coyote 5.0L V8 to breathe more efficiently. The included XX-Pipe (P/N 14327) enhances exhaust scavenging and produces a sharper, more refined performance tone. The dual-wall, slash-cut 4.0" polished tips complete the quad-tip look for a bold, track-inspired rear profile.
⚠️ Fitment Note:
Fits Premium Package models ONLY and requires a Roush Quad Tip or similar rear valance modification for proper installation.
