Stock is 3" turbo back. To 4" I believe but I could be wrong. No real performance difference 4" versus 5". But like lukesdiesel said, just sound (and price)

4" with 6" tip is what my dad's 01 has and it sounds great, deeper than my 04 with 4" and 5" tip.

On my first truck I had 5" to a 6" tip and loved the deep tone! Never rode in one with a 4" so I have no real comparison to the sound difference inside the cab.
