Those of you with Apex-i WS catback, I need your help please. I have a 1997 Maxima SE and I am getting ready to install a Cattman Y-pipe and Apex-i WS catback system. The Y-pipe comes with threads for installing the two oxygen sensors from the stock Y-pipe. I need to know how to go about getting the oxygen sensor from right after the catalyst converter on the new exhaust. Apex has not provided a thread for the factory oxygen sensor. Thank you for the help in advance.

Re: rear O2 sensor for 97-99. Have the muffler shop make a fitting at the front of the B-pipe section to allow for the 02 sensor.
