I was able to access my N55 manual online. Here is a pic right out of the manual to get a better idea. Also I attached pics of my stock exhaust, you can see the 2 resonators as well.

This is what I mean about the 2 cats in 1 canister. Ceramic structure 1 has 600 cells and Ceramic structure 2 has 400 cells



Here is my stock stuff after the downpipe.
