O2 sensors in exhaust

Maybe this has been covered elsewhere, and if it has, i apologise!
I have just bought a new exhaust and cat pipe for my mini one, it was blowing at the flexi joint.
Planning on changing it early next week, but from prior experience i guess i will struggle to get the lambda sensors out of the pipe!
I was planning on replacing both while i am at it, are they both the same? Or are they different sensors?
I see some on ebay for £30, should i be wary of them? Or will they be ok?
Thanks

Hi ya

You may find when you come to do the job you only have one O2 sensor on your mini one it was normally only the cooper s that had two. The one post cat normal has a blanking plug in it.
I have changed a few and never had a problem getting the O2 sensors out, just use something like plus gas (penetrating oil) and the correct tool should not have a problem

The hardest bit about changing the manifold is undoing the nuts at the cat joint again a good penetrating oil and heat normally fixes it but I have had to cut a couple off.
