Mustang GT's and some LX's manufactured between 1979 and 1993 that were equipped with the 5.0 litre V8 engine. (Mustang GT's manufactured between 1994 and 1995 were also equipped with the 5.0 litre V8 but are a different body style and normally not referred to as Mustang 5.0's by enthusiasts). Typically, Mustang 5.0's are driven by overzealous teenagers and douchebags. Most people perform all the same modifications to these cars, which has resulted in tens of thousands of Mustang's that all look, perform and sound exactly alike. However, each Mustang 5.0 owner firmly believes his or her car is superior to any other vehicle on the road and will try to race anyone that proceeds from an intersection faster than them, even if it's an old lady driving a Buick Roadmaster stationwagon. More often than not, an aftermarket Flowmaster exhaust has been installed on these cars. On Friday and Saturday nights, Mustang 5.0's can be heard cruising around town constantly in second or third gear, which causes the Flowmaster mufflers to amplify the distinct hollow rumbling sound that is characteristic of the 5.0 litre V8. The touch hole that's driving does this so that everyone knows he or she is driving a Mustang 5.0. If you look at a Mustang 5.0 as it approaches, the driver will probably bark the throttle a couple times and accelerate as they pass.
Justin: Hey Chad, heard your father bought you a Mustang 5.0, any mods?
Chad: Pony rims, 4 inch cowl induction hood, racing stripes, Cobra intake, E cam, Flowmasters. What about your 5.0? Did you do anything to it this winter?
Justin: Hells yea bitch, my shit's the ballin' tits outrageous. I got Pony rims, 4 inch cowl, racing stripes, Cobra intake, E cam, and Flowmasters.
Chad: We are so original! Let's go cruise around in second gear and rev our engines at girls that couldn't tell the difference between a Mustang and a fucking Toyota Camry.
Justin: Sick nasty!
