One of the easiest first mods is exhaust. Most V6 stangs sound pretty beefy with a dual exhaust system. I think the Magnaflows sound the best, nice and mellow.
When you're moddin your ride, don't forget the little stuff...
Fluids - Synthetics will protect better and might even free up some power.
Tune up - it has to run good.
Tires - they keep you stuck to the earth.
Brakes - Sometimes ya gotta slow down...
Suspension - if you can't outrun them, out-handle them.
