Evo III Manifold

[neuralracing]

I just installed an EvoIII O2 housing... should I also install the Manifold? Will I need new gaskets or can I grind out the one I have in there now which is basically new.

Where can i buy the Gasket for the Downpipe side of the O2 housing... the muffler shop put high temp silicon on there since we did not have a gasket

I dont' see any problem grinding, but getting the correct one would be a much better solution (and they're cheep too).

That'll last about a minute

Any of the vendors on this site should have the correct gaskets.

As an FYI, the EVO O2 housing's outlet is at a different angle than the stocker putting much more stress on the downpipe (can snap over time). Remedy is to cut the existing flange of the DP and rewelding at the new angle
