545i Cats (Catalytic Converter)

I have an 05’ 545i, I took a glance under the car but I can’t really tell and I would like to straight pipe it completely. My question is, do 545i’s have secondary cats? All I see is 2 mufflers 1 resonator and 2 cats (which I assume are the primary). If I cut out those 2 cats will there be others (secondary cats) I can leave in?
