You're stuck with Air Raid.
Try one of Matts ported throttle bodies and a catback exhaust.
The Magnaflow systems for the Hemi bolt-on,at least it did to my 2013
There's a 25% underdrive pulley/balancer available from ATI .
Darkknight said something about working on headers for the 4.7,but i think they're still in development stage.
You can go with a higher stall convertor and deeper gears.
There's always nitrous for cheap bang for the buck horsepower.
Check out the Gen 3 posts,there's a supercharged 4.7 in there ,using the Eaton blower.

But if you're looking for bolt-ons that are 4.7 specific,they'res not much available yet
Next question,how much do you want to spend.Speed and horsepower doesn't come cheap anymore
