Hi all could someone please tell me if there’s any difference in a B16 manifold and a B18?

Thanks in advance

Both will fit physically, B18C/B16B JDM engines have a 2.5" outlet, B18C6 have a 2.25" outlet and B16's have a 2.0" or 2.25" outlet, Can't quite remember.
That's the only difference, I'd aim for at least a 2.25" but preferably a 2.5". You will need a different Cat/De-Cat for the 2.5" though.
