Got a RP supercat and ive managed to disconnect the wire part from the stock cat but I can't manage to remove the o2 sensor. Can anyone help me at all? My car is a sitting duck until I can get it off. The rest of the install is pretty simple and basic, the o2 sensor is the hard part.

any feedback is greatly appreciated.

thank you,

The sensor is probably stuck in the CAT. It is really common for the threads to get so stuck that you can't get it out. I had that problem with mine...and I just bought a new sensor for the high flow setup...and left the old one in the stock CAT for when I put it back in for emissions. AFAIK...it was about $120 for a new one.

If it won't come out, it isn't going to come out without destroying it.
I did what dannobre did.
However, one day I decided to see what it would take to get the old one out.
Essentially, it took about 900 ft/lbs of torque (8 foot section of schedule 40 pipe on an 18", 1/2-drive breaker bar with a very deep 22mm impact socket) to destroy the threads enough for it to release itself.
The threads in the bung seem to have survived, however.

I managed to get it out after soaking it in WD40 unfortunately now, I have a CEL. anyway to clear the code? I know to take it to pep boys/autozone etc etc to get it read. but after getting it read is there anything i can do to clear it?
