Magnaflow si/do kit. 2.5 inch pipes all around with tips. It sounds good for a 3.0. Sounds like a v8 at idle. It sounds pretty good even at higher rpms, almost like a v8, but not quite. Its not too loud either, which I like. Dont want to attract the cops attention too much.
i have a 3.0 with a 2.5" flowmaster dumped. i thought it sounded like a V8 until i actually got my 5.0 mustang. i hate the sound of my truck now compared the the stang with the magnaflow catback i put on it.
