SYS 11-14 MUSTANG V6

Wake up the performance and sound hidden in your 3.7L V6-powered 2011-2014 Ford Mustang with a Flowmaster Force II® exhaust system. These moderate sounding systems retain the dual exhaust system outlets and are designed to replace the original rear mounted mufflers using factory hangers and connections. With easy fit in mind, these systems are mandrel-bent stainless steel for maximum performance and include specially tuned pair of 60 Series™ performance mufflers with large 3.50-inch polished stainless steel tips. As a Force II system, it delivers a moderate exterior tone and a mild interior tone and is suited to the enthusiast who wants a subtle but distinctive performance exhaust note. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage. The exhaust is a true bolt-on system, includes everything you need to easily install at home with basic hand tools and is covered by our Lifetime Limited Warranty.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
