Does the removal of o2's because of an offroad y-pipe cause my car to get way less gas mileage?

I'm assuming you mean rear o2s. No removing the rear o2s shouldn't affect your gas mileage. Removing the front ones will however.

The rear 02 sensors are just there to monitor the catalytic converter's efficiency, they in no way have a role in fuel delivery.
