Factory exhaust might be 4" but its not mandrel bent and has lots of kinks. A good full 4" or 5" turbo back exhaust is a great place to start.

And how much HP does he stand to gain?

He will gain a few HP but the biggest difference will be exhaust gas temps will be lower.

Actually, unless it's a 04.5 Cummins "600", the exhaust is only 3.75", has a lot of unnecessary bends and the huge stock mufflers suck ***. Like Luke said, there's not a lot of power to be gained by going to a 4-5" exhaust with just a programmer/module but he'll see a significant reduction in Exhaust Gas Temps, especially when towing. Same with an intake. Plus, he'd already be set up should he decide to upgrade to more aggressive fueling in the future.
