Hi there,

Just wondering if anyone knows the ID & OD of the runners used on the OBX intake for the B series?

I'm looking to buy one to chop for an ITB project (it ain't much use for anything else) and was wondering if anyone had the sizes? Even the outside diameter would help a lot.

The type of manifold i'm talking about is here:

Any help would be most appreciated,

Thanks
