Both of your problems seem normal to me. The first one is your motor revving at around 1750-1800 RPM's to get to normal operating temperature so you hear the AEM V2 that you have on your car suckin' in air.

The second one is just what happens when you get water on your exhaust. My exhaust does that too when I drive in the rain. it tends to rattle for some reason.

Your problems are normal IMO. relax

No its just when our vehicles are started cold the ecm will hold the rpms up around 1750rpms to warm up the car that much quicker. Those higher rpms are what makes the noise from the cai much more noticeable. i wouldnt worry about it.

The intake noise is normal and is because the IAC valve is open quite a bit to keep the revs up on a cold start.

It's the equivalent of straining to suck air in through a straw.

You get kinda the same noise when you shut the engine off.

As for the exhaust and the rain I've read a few threads about this.

My conclusion is that it's the effect of the cold water hitting the hot exhaust.

The exhaust expands with heat and contracts with cold. So when the hot exhaust gets blasted with cold water it wants to contract when the hot exhaust gases are still making the metal want to expand on the inside.
