Visual Differences in 1g and 2g o2 housing

[Dream On]

I know the 2g flows more, and I'm planning on getting one, but I need to know if there is anything that I would be able to notice so I make sure I'm getting a 2g and not somebody trying to just sell me a 1g housing, since I can't really compare the two side by side since mine is still on for now, and people just send pics of theirs. Hope this makes sense...thanks in advance.

So i'm guessing it just looks about the same then, with bigger opening? Any dimensions on the differences of the openings?

Sorry bud, i dont have any pictures but i can offer some info. You should be able to look at your 1g O2 in the car and then look at the 2g, you will see a noticible difference. Also, correct me if i'm wrong, but the 2g has the O2 sensor bung close to the downpipe while the 1g has it closer to the turbo.
