W220 S65 exhaust
I took the exhaust out to take it to the shop to do the cat delete and found only this 2 cats. I read about primary and secondary cats but it was only this amd the resonators in the back. Is this the way it comes or it was modified already?

65s have only 2 cats and mufflers. There are no resonators or secondary cats. That's a stock setup. Try to make a new air intake setup to allow you catless exhaust to breathe. You will feel the car run out of breath over 4k rpms with the stock air boxes. Good luck, and enjoy.
