For many owners of the restyled Mustang GT, being noticed on the street is as important as how the car performs at the track. Fortunately, being noticed just got much easier, with the introduction of Flowmaster’s Outlaw Axle-back exhaust system. Featuring the race-developed and proven Outlaw mufflers, and finished with polished, embossed 4.00 Inch diameter tips, this easily installed system gives the 420 Horsepower 5.0 a very aggressive tone inside and out, with moderate interior sound at 1800 to 2000 RPM.
