Doe anybody know the outside diameter of the outlet of a yamamoto half system off hand?

My system has yet to arrive, and I plan to go to an auto jumble tomorrow, and don't want to miss the opportunity of finding a suitable end can for it. You never know?!

51/52mm　maybe.. it's a bit late to go measure mine.. maybe somebody else will know for sure.. it's quite small

Cheers Neo, decent gauge to kick off with.

Just measured one I have lying around, 50mm exactly.

Cheers Cammo,

I went round the jumble on Saturday after having a brief check to find your reply... Had high hopes, feeling optimistic.... But no dice.
On the plus side, my system arrived over the weekend.
