Show original supplier description
The ARMYTRIX Valvetronic Cat-Back Exhaust System offers enhanced exhaust flow and sound for the 2015-2017 Ford Mustang GT Fastback with the 5.0L Coyote V8 engine. This system features cutting-edge valve control technology, allowing you to select between three modes: Smart, Neighbor, and Beast, or customize an automatic mode via a dedicated remote or a mobile app. The app provides real-time monitoring and control, enhancing the driving experience. Constructed from high-grade stainless steel with a polished finish and dual 4.5-inch blue coated tips, this exhaust system incorporates advanced design elements such as an X-pipe, mid-pipe, and valvetronic mufflers. It is designed as a direct bolt-on solution, and the plug-and-play OBDII dongle module reduces installation time by approximately 30% compared to traditional cable wiring. This specific de-catted pipe configuration replaces only one side of the catalytic converter. Consultation is recommended for convertible models to ensure proper fitment, as it is exclusively designed for the 2015-2017 Mustang GT Fastback model.
