Exhaust Manifold Difference

[ian_maham]

I was wondering what the difference is between the 1g manifold and 2g manifold.
-Possible density/thickness.
-Diameter of outlets.
-Same size/No difference?

I am just trying to figure out if a 1g manifold will bolt up to a 7 bolt block just fine. I also plan on having 1g manifold ported. I know the 1g 02 housing is a bit thinner than a 2g, just wondering if the same goes for the manifold.

Trust me I have searched so please don't give me crap. If you know where the info is please post a link or something.

Thanks,
Ian

Lolz. Sure you did ...

Are you familar with the vfaq at all? If not you should poke around.

FYI... 1g manifolds are Very Prone to cracking...

+1 i think the 2g's came with a lil higher nickle content.

2g manifolds have a different runner setup they bring the flow up to make a better transition to the turbine housing. So a 2g manifold is better flowing and is little less prone to cracking.
