My 2010 Xterra Off-Road basically needs a new catalytic converter for bank 2. However I have a total of 4 catalytic converters, 2 on each side.(front and back) I was wondering if anyone knew how I could find out which bank 2 converter I would need to replace without going to a garage. I would like to avoid replacing both if the other is working properly. Can anyone help?

to NICO!

Sorry for the late response. If I'm not mistaken the OBDII code that you pull should direct you to the left or right side... I could be wrong on that though. The best resource would be your trucks factory service manual at www.nissanservicemanual.com
