I just dont want to do this and it causes my car to limp
You need to move your old O2 sensors from the oem manifolds to the new ones. Make sure you do not mix them up, I recommend that you remove the old manifolds with the sensors in place and then swap the sensors one by one from the old manifold to the new ones while you have everything off the car. Mark the wire plugs with tape so you plug each one back in the right spot.

You need to code for the cat delete or you will get a check engine light. You will not get limp mode without cats just a check light.
Thanks, would I have to get the car tuned?
