o2 sensor delete??

Im putting a built L33 5.3l in my miata using an Ls1 motor harness. I will be running a pretty open exhaust and dont really want to have to weld in o2 sensor bungs and buy o2's. Is there anyway I can delete them from the engine harness without having any running problems or check engine light?

The rear o2's you can delete. The front 2 you need to run the engine properly.

So, if I wire the two front ones in and leave the back ones out wont it turn the check engine light on? I wont be running cats either so the back ones wont do any good anyways.

Yup. You will most probably need to get the computer reset to pull those codes from it and anything smog related. After that, the CEL should stay off.
