Default Reccomendations on what diameter tubing foor a custom bent exhaust??

I bought a Apexi N1 turbo muffler(bigger tip+bigger canister, doesnt looks as pinner as regular N1), and i was wonder what you guys would suggest for piping fron the cat back.. This is a street driven car aswell..Would 2.5" piping be sufficient? Or should i just stick with 2.25" exhaust?

Since you have a 3" inlet/outlet on your muffler, I vote for 3" piping the whole way.

It makes no sense to have a muffler with bigger inner diameter than your piping.
