Simple questions for this catless x pipe. For the circles in red, do i simply plug them in with plugs and if so where can i find them? or do they need to be plugged with o2 sensors? For the circle in blue, what is that for?

As long as your tuner does an 02 sensor delete you’re good. Just talk to your tuner to ensure they offer that. Are you planning the build with your tuner? If not I highly recommend leveraging them for support.
Did your own downpipe have two rear 02 sensors? If you plug em you gotta tell the ECM they aren’t there.
okay but if I plug them will I have any issues? I will get it tuned.
