I agree that you could just always get it later. It makes for a fun afternoon DIY project.
The intake is shown to get you 15~20 WHP/WTQ across the rev range. GM doesn't advertise it as adding more power for some reason, but there is someone who did a dyno to show the improvement. A pretty small performance bump for the price, but it is nice eye candy, I agree.

Supposedly, that whine comes from the way the air flows from the intake to the throttle body, and then the intake manifold. The stock airbox makes the whine, but the thick plastic helps conceal it greatly.
The GM CAI has a little spacer plate that goes between the throttle body and intake manifold. It comes with associated gaskets and longer bolts. The spacer plate has a little lip at the bottom, which gets rid of the whine. If you want to hear the whine, just don't install that plate.
