where does the 02 sensor go on a gsr motor? Im swapping a b18c1 in my civic. Its an obd1 b18c1 and i dont know where to put the o2 sensor. I dont see a place to put it on the stock header, so im guessing i will need the stock gsr cat. true?? or false?

true. It goes in the stock gsr cat

Yes it goes in the cat. Most exhaust shops could make a hole in your exhaust pipe and weld a threaded nut on for the O2 sensor if you don't want to buy another cat.
