Where is oem parts guide??
 

I was wondering if somebody can direct me to an OEM parts page for Chrysler Sebrings.. like bmw has realoem.com.

Or, I need a diagram of how the exhaust connects to the engine. It appears there's a plate or pipe came off...

Try chryslerparts.net. Actually, there are several Chrysler dealers who sell parts on the internet via an online part catalogue.
If you have a specific question, give some more information like the year, model and specific engine involved. Maybe someone here can answer your question.

Thanks, I have a 2003 chrysler sebring convertible 2.7l engine..
I just found out they call what I'm looking for a pre-cat, comes 1st out the engine exhaust up front.. went to junk yard yesterday and couldn't find it, then i found out they consider it catalytic converter.. grrrrrr...
