Turbo housing vband sizes?

[bastarddsm]

What's the deal with turbine housing vband sizes. Garret specifically. How are they measured? Does each brand have there own proprietary sizes? Where do you buy the parts? My exhaust is all 3" vbands, but I bought them together off ebay so it's been no hassle.

I have a .96A/R open t4 Ptrim housing I want to use. It's vband out, but it's small. like 2.5"

Silicone intakes has the parts and charts you need. Actually are nice clamps and flanges.
