Exhaust O2 Sensors

[Flagstaff Fury]

I am looking at buying a JDM Cat back exhaust. I don't see any holes for the O2 sensors in the pic. Does the piping come with the holes? I know not having them will make it run like shit. Thanks!

1g's don't have o2 sensors back there. We only have one immediately after the turbo in the o2 housing. You're ok.
