You can get a hole fitted at an exhaust shop, they should be well used to doing that. Or replace the sensor with an O2 simulator.

the simulater just makes the car think it has the sensor in it by controlling the voltage and frequencies that are sent back to the ecu heres a link to one on fleabay. and needs soldering into the system.
