Conflicting info on 2008 Kawasaki ER-6n catalytic converter location – Is it in the headers or the muffler box?

Hey everyone, ​I'm planning about doing some exhaust work on my 2008 Kawasaki ER-6n and I need some definitive answers because I'm finding completely conflicting information online.

​My stock exhaust is a 2-piece setup: the header pipes come down from the engine, merge into one, and connect to the big under-engine muffler box via a clamp/band. The O2 sensor is located on the headers right before this clamp joint.

​I want to install an aftermarket slip-on, but I want to keep the bike legal and eco-friendly, so I do NOT want to remove the catalytic converter.

​Here is my dilemma: ​Some sources online claim that the cat is located at the very end of the header pipes (right before the clamp). ​Other sources claim that the cat is permanently welded inside the actual stock muffler box ("the big box"). ​If I remove the stock muffler box and put a slip-on on the stock headers, am I deleting the catalytic converter or is it staying inside the headers?

​Has anyone with a 2006–2008 model cut their stock exhaust open or replaced it and can confirm 100% where the cat actually is? I don't want to accidentally do a cat-delete. ​Thanks for the help!
