I have a wideband i want to install as i have greddy ultimate now. My question is, without removing any parts from car can i have an O2 bung welded in? Anyone have pics of where?

I have stock header and cat. But i need o2 before cat. Is our header double walled or not? If so is there space before the cat for it?

Please let me know soon. I need wideband in ASAP as i have EMU in with a empty map in with all settings in, and i started getting knock on interstate today (CEL was flashing and loss of power) and when i stopped and turned car off, then back on it was fine. Was cruising at 4400rpm in 6th gear when it did it. First time its done it and iv driven over 200 miles with the greddy in already.

 

I have my wideband 02 sensor mounted in the stock header. Ideally you want it mounted on the top side of the pipe pointing down, so they will have to take the header off to weld in the new bung.

 

Ok, so it isnt double walled then. So it is possible, just going to be crunched for room. I know he wont want to take the header off unless its a easy job.
