I have an evo 3 on my car with an Ebay 16g. It bolted up just fine. They are a direct swap.

I have run both. They're both direct bolt-ons and people have run 10s with both. Evo 3 is better but more expensive and requires a small amount of trimming. 2g EMs are cheap enough that there's really no reason to run the stocker. If you're gonna port one don't waste your time on a 1g EM, spend the $20-$40 on the 2g one then port it.

Both are bolt on. 2g is bigger but EVO III is the biggest stock looking one. You can also get the EVO III O2 it's also bolt on but you'll have to modify your down pipe a lil.
But yeah def toss that 1g Mani they are prone to cracking and are made of a crappier material than the 2g ones and EVO III.

did anyone who is running the EVO 3 exhaust manifold and O2 housing have any have any issues with the stock turbo and exhaust hooking up because of the placement of the 02 housing outlet? do you just need to adjust the exhaust pipe a bit or what needs to be done to run the Evo 3 exhuast manifold and o2 housing? on a otherwise stock manifold and exhuast set up

Yes they both work the same as stock as far as bolting up to your turbo. Only the corner of the flange on the Mani needs to be trimmed, and when I say modify the downpipe, I'm talking about just merely changing the angle of the flange that bolts to the o2 a lil. That's all u have to do to enjoy those free flowing Jdm parts.
