Where does the o2 bung go on a 2000 Civic EX? Would be AWESOME if someone happened to have a picture of where it goes so I can tell the muffler shop where to weld the bung onto it. I was just told that one goes before and one goes after....but where after the cat? Does it matter? A picture is worth a thousand words as they say, that way I know exactly where it goes. Also, how can I get to it. I saw that it went up through a hole in the bottom of the car but couldn't see it through the engine bay. Help would be much appreciated.

like 3 behind the cat is fine. of course dnt put it where there is tension in the wires or where itll hit the gorund or body of the car. if they dnt know where to put the bung i wouldnt be having them wrk on my car. plain and simple. god luck with that though. lol!!!
