Exhaust 2011-2014 Catted Xpipe V6 Mustang with 2 front oxygen sensors. 6 months old, approx. 2,000 miles, Good condition. BBK Exhaust. Putting car back to stock so I need to sell this one. I plan on selling the car I had put this on and took it off to sell. I take great care of my vehicles and have a top mechanic do my work, so this exhaust is in prime condition and ready to install.
