Right did some searching on here about decat on agu. Do i need to map out lambad sensor?? And if i get decat and downpipe would that not get rid off middle box few threads are talking about getting another straight pipe to get rid of the middle box .. I have a custom catback at the moment

No, AGU only has pre cat lambda so wont know if theres no cat there or not!

Will i need this middle pipe too iv read abou on few period threads

The racetube or de-silenced centre section is ideal aswell.....the more free flowing the better!

I just did mid silencer bypass done feels more freeflowing, going decat as well soon. Either 2.5" or pikey method of smashing a spare cat up.

With mid silencer by pass the agu back box and mid silencer is one piece, so be prepared to cut some pipe. Get a diesel piece they are around 15-20quid, its the same thing as race tube.
