This is my 2002 Mustang GT I got October 6, 2007. As far as modifications/upgrades it has Flowmaster mufflers(video below), a BBK cold air intake, mach 1 delete, JVC head unit, and an 18" shorty antenna. This car also came from the factory with the mach 1000 stereo system (1140w max), which includes a 6 disc in-dash cd changer, 8 speakers, and two 10" subs. I replaced the factory head unit with a JVC HD Radio one.
