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 single 4.5-inch Polished Pro-Series Tips. Designed for Mustang GT enthusiasts, it offers selectable Xtreme or Sport sound levels to match your driving preference and engine setup.
Constructed from 3.0-inch mandrel-bent tubing, this Cat-Back replaces the factory mid- and rear exhaust sections for improved flow, reduced backpressure, and a more aggressive V8 tone. The dual-wall, slash-cut polished tips enhance rear styling with a premium, motorsport-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 highly aggressive engine modifications due to volume.
-
Sport Sound Level – Controlled aggression with 7 lbs weight savings, ideal for pairing with aggressive engine modifications to manage overall exhaust volume. Includes XX-Pipe P# 14327 and Touring Axle-Back P# 14329.
The system is bolt-on, using factory mounting points for secure installation without cutting or welding, delivering enhanced performance, aggressive sound, and premium styling.
