I installed a high flow catalytic converter in my S2000 and now it's triggering an oxygen sensor code. Can I use a different sensor to allow for the increased airflow? Has anyone had similar issues?

 

First make sure you plugged three o2 sensor in correctly, then go to your local auto parts store and pick up some spark plug defoulers, there one package with two pieces, get a 1/2 inch drill bit and widen one of the pieces your secondary o2 sensor will screw into that one, next install the UN modified piece into the bung, tighten it then screw in the o2 sensor With the modified piece into the other plug the sensor in and Erase the code.
