Evo III manifold vs. 2G manifold

[90BLKTALONTSI]

I got a quick question for you guys. Are there any visual differences between the Evo Exhaust manifold and the 2g exhaust manifold? I recently bought a exhaust manifold off of ebay and was told that it was an evo manifold ported at the collector but I just want to make sure. If there aren't any visual differences, are there any performance differences? Thanks in advance...

You can't really port the collector anymore than the 7cm it already is, just smooth it out. I will be bigger that a stock 2g manifold and the collector no doubt.

There is a pic on this page of an EVO and a 2G next to each other. Check it out and see what you have.
