Any ideas what it is, just before the TB? Gonna do a cold side relocation as i have some straight pipe left over from another project, but wanted to use an ali T piece until I go FMIC some time next summer (or the one after that...)

Like this?

Outside diameter of the T is 50mm. This is from the Forge DV relocation kit.

Yep! Exactly like that! I'm thinking 63mm?

EDIT: Ooops, 50? Blimey that's small! Thanks Rob
