Will my O2 sensor even know its gone seeing that it is in my exhaust manifold.
I am also worried about the absence of the back presure.
You're force-feeding the engine, so backpressure isn't as serious of a concern to begin with. First, your O2 sensor won't have a clue the cat is gone. If you're planning on keeping the 2.5" diameter pipe, and adding a flowmaster, I know you'll be ok with removing it. You won't lean or rich out at all, 94 only has one O2 sensor. You're in luck.
If you go 3", you still probably won't have a problem. If your backpressure gets too low, simply plop on a 2.5" SC pulley and make up the difference. A good intake too. With all that, you'll be fine. SSEi95 is a good example of what you can do.
