7afe ebay Header MOD?, O2 sensor in the wrong spot Options

[RY0BI]

Now i bought the current Ebay header for the 94-99 celica which mine is a 96. Now my engine does have a cat but it is not off the exhaust manifold it is past the mid pipe, no worries there. Other than that it will take place completely of the one i have and everything looks like it will bolt on directly. The only difference is that the O2 sensor that they have on the ebay header has the bolt on style O2 sensor and mine is the screw in one. Also my current position is a lot lower on the exhaust manifold and reads all 4 cylinders where as the ebay header is on the left and reads only one cylinder. Someone has had to run into this. I know i could plug the bolt on hole by making a plate but what about my O2 sensor it would have to go much lower on the header to read all 4 cylinders? If I just keep it unplugged will it make my car run like crap?

Thanks in advance for the help

Ok maybe I should have read the ebay posting before I listed it, no matter here is another one, and maybe this is better

Well its the same freekin header or at least the same design, it looks exactly what I have minus the better pipe lining than the exhaust manifold, it will bolt exactly to my existing exhaust without an extending piece, and only has one O2 sensor which needs to be moved, Being that it is stainless can i weld a regular bung to it and where do I weld it on the 2 pieces where it will read the best? The pipe is still kind of split right before the flex pipe and after that were going to the bottom of the engine.
