This aggressive sounding Flowmaster American Thunder system for your 2013 or 2014 Mustang GT features Flowmaster's 60 Series mufflers with 4" diameter polished 304 stainless steel tips embossed with the "Flowmaster" logo. This kit gives your Mustang style and power, with a mean, American muscle car growl to top it off. 


This kit is designed to replace original rear mounted mufflers located behind the factory catalytic converter using factory style connections. With easy fit in mind, these systems feature mandrel-bent 16 gauge, 409 stainless steel for maximum performance and durability. As an America Thunder system, it delivers an aggressive interior and exterior tone and is suited to the enthusiast who wants a distinctive and powerful exhaust note. Like all Flowmaster® systems, the benefits include improved throttle response, power, and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.
