Lambda sensor

[e12mat]

Right Bank, even lambda sensor needs to be changed. The odd bank exhaust manifold sits lower so it looks like it would be easy enough to change, however the even manifold sits higher.

What's the tried and tested method?, I done a quick search but couldn't really find anything.

Is it to remove the cat to allow the manifold to drop slightly to give just enough space to remove?

Any help is much appreciated!

I found removing the cat gave more room Plus a stubby 17mm spanner would help lots.
