Description
Upgrade your 2015–2017 Ford Mustang GT 5.0L V8 Fastback with this 3.0-inch Cat-Back Exhaust System, featuring dual rear exit and 4.5-inch Single Polished Pro-Series Tips. Engineered for the S550 Mustang GT platform, this system provides selectable sound levels—Xtreme or Sport—to suit your performance needs and driving style.
Constructed from 3.0-inch mandrel-bent piping, this Cat-Back system replaces the restrictive factory mid- and rear exhaust sections, improving flow, reducing backpressure, and delivering a sharper, more aggressive V8 tone. The dual-wall, slash-cut polished tips enhance rear styling with a bold, performance-inspired finish.
Sound Level Options:
-
Xtreme Sound Level – Maximum aggression with 12 lbs weight savings. Includes XX-Pipe P# 14327 and Sport Axle-Back P# 14326. Not recommended for vehicles with aggressive engine modifications due to volume.
-
Sport Sound Level – Controlled aggression with 7 lbs weight savings, ideal for pairing with aggressive engine modifications to maintain balanced exhaust volume. Includes XX-Pipe P# 14327 and Touring Axle-Back P# 14329.
The system features bolt-on installation, reusing factory mounting points without cutting or welding, providing OEM-quality fitment while significantly enhancing exhaust performance, tone, and rear-end appearance.
