Sorry I did rush my question so rushed/sarcastic answer accepted I have had a quick look underneath but could not spot it, just looking for a picture to highlight where it actually sits and how to remove it. Cheers,

I wasnt being sarcastic. There must be 12" of pipe between the cat and manifold...you might even be just about able to see it from the engine bay.

To remove it you need a lambda sensor socket. If the sensor is seized in the pipe the sockets can flex and open up losing grip of the sensor. Sometime a big spanner is best. If the sensor is going in the bin just cut the cables off it and stick a normal socket over it to remove. That wont slip off the sensor.

I just use a normal spanner, never failed although sometimes a mallet helps on the spanner to loosen it up

Thanks, definitely cannot see through the engine bay the outlet manifold on these seem well hidden, unless the car is raised properly in a garage I guess. Cheers for your help guys.
