Flowmaster introduces our Flow FX stainless steel axle-back exhaust system for the 2011-2014 Ford Mustang with the 3.7-liter engine. This system uses a Flow FX series muffler for a moderate to mild sound level and increased performance. Mandrel bent 2.5-inch 409 stainless steel tubing allows for maximum exhaust flow and durability. The system uses larger 4.00-inch black ceramic-coated stainless steel tips for a custom look. Max dyno gains of 7 hp and 6 lb-ft at the rear wheels over stock. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
