The lambda sensor issue may not be the sensor itself.
The 2.0JTS had issues with the lambda sensor connectors from day one. Most of the time it was those, not the sensor itself.
As for the centre silencer. stick a patch on it. If it has a leak it may cause the tailpipe probe to pickup emissions out of range and cause a fail. It in't so much about exhaust leaking out, it is extra air getting in that changes the tailpipe reading.
Check those brake pipes too. A sudden brake pipe burst is unlikely to end well......
