get a bung welded in
noob question what happens if he replaces the rear 02?get a bung welded in
I'll get a CEL that sticks around even if I disable the rear O2 in the ECU. I'd like to not get a CEL (hence the HFC) plus it's not good to have your wideband O2 sensor after the cat. I'm sure you don't want the stock front sensor there either, so there's really nothing to do with that bunghole (heh) except keep the rear O2 sensor there.noob question what happens if he replaces the rear 02?
People get them welded on before they order their parts. Or the parts come with the extra bung.Really?? So everyone who is installing an AEM UEGO is either going with an aftermarket downpipe or welding a bung into their stock downpipe?
I have the Cobb HFC, which only has a bung for the stock rear O2 sensor, and not enough room before the HFC for an additional bung to be welded in.People get them welded on before they order their parts. Or the parts come with the extra bung.
What HFC do you have?
Ahhh, yah just get a aftermarket DP or cell the HFC an get a different one.I have the Cobb HFC, which only has a bung for the stock rear O2 sensor, and not enough room before the HFC for an additional bung to be welded in.

About how much is it to get a bung welded on?get a bung welded before the cat. if u drill into the cat make sure the bung is SS. But i would just weld it to the dp Make sure the bung is in a location that doesnt interfere with the flow of the air going to the first 02 sensor.
user from another forum said:I removed my rear o2 and run my wideband in the rear o2 spot. It works great for me, the delay is only .1 of a sec if even that much.

a bung cost me ~$3 from ebay and another $10 to the local muffler shop to weld it on (i already drilled the hole before hand). this was cheaper and imo the better route to go. getting the down pipe off the 1st time can be a huge pain in the ass though.About how much is it to get a bung welded on?
You can run your wideband in the rear O2 sensor bung IF and only if you are running a test pipe
