How can I tell if it's a 1g or 2g exhaust manifold?

[Ervin_S]

I know that the 1g turbo manifolds are more restrictive than the 2g's but is there any other way that I could distinguish these 2 manifolds? Perhaps there is a slight difference in design or something like that?

Any input is appritiated.

The 2g manifold has what looks like webbing between exhaust runners, and you can tell when it's a 1g because it has cracks in it
