Ok so I took some pictures because I heard a leak start up about 2 days ago. I noticed it was coming out of this area and the gasket that was there pretty much broke apart in my hand when I took it out. That and the catalytic converter was red hot one night and the SES light is on. blah blah. So yes help this n00b find out what the heck this is.
These guys are right, your cat is either blown or about to be blown. You may also be running rich. Do you hear any pinging or rattling when you drive? That piece is the EGR inlet tube. It sucks exhaust back through and deposits it, I think in the intake manifold. So it'd make since why the gasket fell apart in your hand. If the cat is clogged the exhaust has to go somewhere. Back up your headers/ehxhaust mainfold and out any hole it can find. That being your leaky sound. I suggest you go have your codes pulled.

My car rattles (thought it was exhaust) and has the CAT O2 code... Could my car be running rich and causing the CAT code to go off?

A rattling cat and code typically means your cat is clogged or going bad. Running too rich will cause the cat to go bad, but the only way to fix that is replacing it or gutting it out and deleting the code.

I dont think its the CAT rattling. Ive tapped and hit it and it made no noise, I only hear it when the engine boggs down (need to drop a gear or not enough gas taking off in first) or when Im really getting on the gas...

Either way, you still have a code saying that your cat isn't functioning properly. I would get this checked out.
Yah I checked around seems like I need to call the dealer to get that damn gasket.
I only noticed it glowing red when that gasket fell apart. I dont hear any rattling and i've tapped on it a few times. The cat is only 1 year old it was installed with the entire exhaust system.

You can get some RTV and carefully use it in place of a gasket. It can be messy if you get careless, but if done right should seal.
My catalytic converter didn't rattle when it went bad. It didn't even throw a code. The only way I knew it was bad was because the car was considerably sluggish under load and didn't want to accelerate past a certain rpm. Other than a glowing red cat, one way that you could probably tell is to start the car and try to feel how much exhaust is moving through the muffler and out the tips.
