New 2002 Dodge Ram 1500 4.7L V8 4x4 performance upgrades?

[zRobx71]

I'm about to buy a 2002 Dodge Ram 1500 4.7L V8 4x4 and 4.7L isn't that great from what I know which is hardly anything. So I was wondering what I could do to it that are simple upgrades like air intakes and exhaust. I have no idea what brands are good for cold air intakes and I know that this truck already has a glass pac on it I just don't know which one. I was thinking maybe I could take off my Flowmaster 40 muffler off my 1997 C1500 but I don't know which one is better. So on top of those two things, what else could I do to upgrade my new truck's performance?

I'd start with a bigger cam, cold air intake, true dual exhaust. Depending on how much $$ you have to spend. Don't waste your money on tuners with this engine. Not a lot they can do to help our trucks (o2's).
