Do I need 2 catch can, or is one good enough?

[D’MO]

Hi, I have a 2022 Kia Stinger GT 3.3 liter. I want to install a catch can but I was wondering if 2 of them will be necessary or will 1 be just fine? I’ve seen people do it either way but I just wanted to be sure. Thank you!!!

I have the single on the passenger side PCV, its a single intake from both turbos so I wasnt overly concerned with a second.
Maybe someone with 2 can comment on how much the 2nd CC actually removes or how it compares for volume from the passenger side CC.
