Get That Unmistakable Flowmaster Sound For Your New 5.0

If there’s anybody out there with a Fox Body 5.0 that hasn’t run Flowmasters on the car, we haven’t met them. It’s only fitting then that Flowmaster’s got an American Thunder Axle-Back kit ready to roll for the new 2011 5.0l Mustang GT. Like all of Flowmaster’s systems, it’s a true bolt-on, and it’s made from mandrel-bent 3-inch 409S stainless for durability.

Original Press Release:
The Ford 5.0 liter engine is back and delivers an incredible 412 Camaro-smokin’ horsepower. To match the factory’s re-issue of the famous 5.0 liter nameplate, Flowmaster set about re-engineering their American Thunder system to deliver that classic 5.0 liter sound along with additional fuel mileage and power. This new Flowmaster American Thunder Axle-back kit for the 2011 Ford Mustang features a pair of stainless steel, specially built Classic Two Chamber mufflers that provide a very deep and aggressive sound level and is suited to the enthusiast who wants a distinctive and powerful exhaust note. The system is constructed with mandrel bent 3.00″ diameter 409S stainless steel tubing for maximum durability and includes a 4.00″ diameter polished tips with embossed logo that exit through the factory rear valence cutouts. A true bolt-on (Flowmaster engineers pride themselves on creating the best fitting exhaust systems available) that includes everything you need to easily install at home in your driveway with basic hand tools. As with all Flowmaster products, they are built in the USA and backed by our limited 10-year warranty.
