2G ported is the same as the EVO3 manifold. Check out some pics on google of the differences in the collector area, but not much. Same fitment, different price!

Probably a good idea to invest in some slightly longer, newer exhaust studs, as the 2G/EVO3 manifold is much thicker at the flange. I got all but 1/2 a thread to seat with a copper lock nuts, no washer.

2G 02 housing will maintain your 1G exhaust orientation at the downpipe, and EVO3 02 housing will tilt the top flange on the downpipe, requiring a cut and weld to suit.
