Ok so when i'm driving there is a loud whistling noise. It kinda sounds like the noise a CAI would make but I still have the stock box/setup. Was wondering what the possibilities are of it being an intake leak. It just really stands out while driving (more air flow).

i have/had something very similar. It started after I put on a ported TB, but still exists now that I have the stock TB. I think the gasket needs to be changed. I know i overtorqued the bolts.

hmmmm, i'm all stock though. Besides the e-fans of course. i've never removed anything, i believe there was an issue w/the 03-04's w/intake leaks. Not saying the it could be leaking around the TB though

Your problem is with your bug sheild (there was a TSB about this). The bug sheild causes the wind to catch the windsheild weather stripping and makes it whistle. Peel back your weather stripping on your windsheild and either put double sided sticky tape on or inject silicone in there. Press down firmly. If using silicone let it ooze out and dry. Then take a razor blade and trim/scrape the excess off. Works like a charm and no more whistle
