Cast O2 Housing Comparison

left to right 1g, 2g, evo3

That 2g looks ported. Not a fair comparison...

I was about to say the same thing, the walls on that 2g one are way thinner then all of them.

All 3 are ported. More work was done to the 2g. The EVO 3 can easily get ported to 3" at the bottom. It already starts way bigger than the other two. I'm going to take stock out of the title.

You can go that big, but then your gasket won't last long. Not recommended or necessary on a daily driver.
