is there actually 2 o2 bungs and you might wanna check fitment cause there have been numerous problems with the headers for the accent...

the first o2 bung is on the right 2-1 collector (facing the header) and the secon o2 bung on on the top right after the flex pipe. Which in other words means that I will still have to get the 2 bungs relocated. unless I can use the second location for the first sensor and get a bung welded after the cat? Would the first sensor be too far down the pipe???

I used the first sensor location for the first o2 sensor and I got another o2 bung welded after the cat. Before I got to extend the second o2 sensor wiring, I had it located in the second bung that EF welded after the flex pipe and the CEL came on on my way home. Got the wiring extended and that bung plugged and used my new bung that they welded and I have yet to get a CEL ... I guess I'm good to go.
