Official 2.4L Performance Modification List
Special thanks to PenguinPIE and all the CSS.net members that helped, and the original thread found here, for a majority of the information. 
Intake: The stock air box is highly restrictive. Freeing this up would provide more air for combustion and increase power output
Exhaust: The less restrictive an exhaust setup is, the more power will free up from an engine. Our 2.4 stock exhaust system is decent (has 2.5" piping), but it is restricted by the header, cat (in the downpipe), and the exhaust section from rear wheel back (which becomes 2.25" piping and has a restrictive muffler)
Engine: (requires tuning)
Pulley
Transmission:
Tuning: Our stock engine tune is rather conservative. Tuning parameters like power enrichment delay, air to fuel ratio, and spark timing will result in decent horsepower gains. Tuning after installing bolt ons (intake and exhaust) will further bring out the potentials of those modifications

OK I think I got everything that wasn't added from the last thread. If you see something missing or a link that doesn't work just post it up and I'll add it. Also if you have a video clip or picture of your exhaust that isn't already up please post the link and I'll add it.

Everything on CTIs website says N/A. Are they not producing parts atm?
Also, JBP doesn't sell outside of its dealer network, which based on the links on their site, no company seems to carry their products. I searched through the dealer links and not a single one has JBP cams (or anything that I could find).

The stock manifold is fine for bolt ons. As for the intake its a matter of personal preference because the SRI and CAI make just about the same amount of power.

Quick question, what would be an example of that personal preference between SRI & CAI?

I don't know about the altanator pulley but the underdrive pulley does. Do a search I'm know there are a few threads on the topic floating around.
