Which cats for a muffler bypass pipes system?

Which cats for a muffler bypass pipes system?
From what i heard in youtube, i think that the sound of the sport cats with straight pipes is in the limit of my capacity for driving. Now the real question is: which cats??? Keeping in mind that the OE cats have 600cpsi and 118mm diamater, i have to choose between these options:
1. 120mm (OE size)
2. 130mm (4L engine cats/ FVD size)
3. 150mm (5L engine cats/ Europipe size)
I have to choose also between 100cpsi or 200cpsi, but i'm leading more for the 200cpsi, to make it a bit "quieter" (if possible because it won't have any catback muffler/restrictions), and to prevent any cel light (it still will have secondaries O2 sensors extension).
