What y-pipes are my options

I just picked up a set of hooker long tubes and was wondering if I had to use their y-pipe or if I had options. Also the headers also did not come with O2 bungs so where do I need to properly place them on the headers? This is all going to mount to a Borla catback system if this matters.

I think Jet Hot will fit. Pacesetters should be different. I'd recommend using theirs or having a custom one fabbed however with no/minimal fabrication any LT y pipe will fit.
