Gaskets are used that far down the exhaust because Nissan chose to have a joins in the OEM exhaust there. Regarding replacing the gaskets, I personally would rather replace them with cheap generic gaskets than risk having to do the job twice.
In the UK any exhaust leak is a fail on the annual test (MOT).
