Today I tried to remove the old one (which had broken wires and wasn’t even connected) and replace it with the new rear O2 sensor that I got from Nissan.

Problem is, when I tried to remove it, the sensor snapped and now I have the tip of the sensor stuck in the downpipe which is still threaded in… There’s no exhaust leak, but I would really like to replace it with a new one.

Any idea if I can remove this w/o cutting, welding etc… ? Or should I just bring it to my mechanic?

Thanks.

i would just drill a new hold and weld a bong, thats the easy way.

the right way is to remove but its almost impossible.

Or get a replacement dp - take one out, put the other in - I can sell u my spare for $10 or trade for something cool for my s14 (dp has the bung but doesn’t come with o2 sensor). PM if interested.
