Evo III o2 housing

[Merlin Beerens]

how big is it stock? and how big is it ported? and does anyone know if an apex n1 downpipe will bolt right up to it? thanks

im lacking the sizing info but no the Apexi N1 Downpipe will not bolt right up to it... the EVO o2 housing flange is on an angle the stock one isnt...

I have an EVO III o2 housing. It is at an angle, but you can bolt it right up to my 2.5" buscher dp because of the flex section.
Mine is ported and is fookin huge!

ahh i forgot about that.. so the answer is maybe... the flex section might allow you to bolt it up

In case you haven't seen them, RRE has comparison pics between the stock piece and the EVO III housing.

Just scroll down to the EVO manifold and O2 section.

As long as there is a flex section in the DP then it will bolt up. I have the same problem with my O2 housing from XSE
