I think there's something terribly wrong with a 5.0 or a Mustang in general that you can't hear BEFORE you see it. That doesn't mean it has to be obnoxiously loud, but i think they should all speak with authority. My car borderlines more on the obnoxious side (MAC LT's, Dr. Gas X pipe and 1 Chamber Flowmasters "backhalfed" with no dumps) but when i drive my car it's a whole experience, i don't drive it because i want a cushy and comfy quiet ride, i drive it because i want to have fun getting from A to B. When i start it to go to work (i work 3rd though) i usually set off most of the car alarms "warning signals" in the lot, but they usually don't go totally off unless i tach out while i'm next to them.
If i drive through a parking garage it's ALL over....i have some wierd health issues and i have pretty routine doc visits, and i have to see these insanely over priced doctors (neurologists and brain sugeons) so the parking garages are almost always filled with really expensive cars, i've even seen a few Rolls Royces, Ferraris and at least 2 Gallardos....so it's kind of a poor man's revenge when i set off all their alarms...lol
I wouldn't say i'm young, i am only 26 but guys i've lived a F'in hard 26 years (hence the health issues) so to me having a crazy car is a way to cut lose and get rid of stress. If it pisses other people off, well they can try my shoes on before they judge me ya know?
