Ok, first, my car is a '99 2.0 AEG 5 speed. I have been addressing exhaust issues. Namely a new cat and upstream O2 sensor. Then I noticed the manifold has cracked. I found one at a pull-a-part however it is different in that it does not have an O2 port like my original did before the flange for the down pipe. Do some of these cars have the Upstream O2 sensor in the down pipe past the"Y"?
