R56 Catalytic Converter(s)?

Catalytic Converter(s)?
I have researched extensively, including online, in service manuals and interviewing mechanics and I cannot seem to get a straight answer.
I have a 2012 MCS stock exhaust all the way, and was wondering who could tell me if there is more than one cat in the system?
I understand that there is one in the downpipe but I have also read about another down the line. And this was on several occasions.
Any and all information is helpful!

The primary cat is in the downpipe and there is a second cat under the car. There is also likely a resonator under the car. If you kneel near the door and look under the car, you will see the exhaust and two larger diameter round pieces. These two larger pieces are the 2nd cat and the resonator.
Have fun,

That's so interesting, I had talked to the mechanic earlier today and he said that the only cat is in the down pipe, and that the other components were resonators. Mind you, this was a mechanic who works for the dealership.
The reason I ask is because I was looking to get a catback, and read in several places that certain ones get rid of this so called second cat. I don' want to void any warranty and throw any CEL's.

I believe the R56 has 2 cats. Please check out this OEM diagram for reference. Hope this helps.

I managed to find the diagrams before but I didn't have my car to compare it to.
I think we had a breakthrough people!
I believe everyone is right and I just didn't connect the dots. (Including the mechanic who might have misinterpreted my vague question)
According to the diagram (attached below) it seems that there are two versions of the stock exhaust, both of which have a cat shown on the left (the one downstream from the DP) and either 1 or 2 silencer/resonators (I happen to have the one with 2). LAME.
Any suggestions on full exhausts/catbacks/DPs?
