This is a Ford Performance Axle-Back Exhaust for V6 Ford Mustang years 2011, 2012, 2013, 2014. I bought it new in November 2016 ($660). It was only on the car for about a month and is in absolute perfect condition. I love the sound and response but unfortunately my wife doesn't, and she drives the car as well. So, OEM is back on the car and this is up for sale. $450. Gainesville, VA
