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?

Did your own downpipe have two rear 02 sensors? If you plug em you gotta tell the ECM they aren’t there.
