Thanks for the info Gonzo....

I was comparing the Magnaflow Catalytic converter to the one listed on Nissan courtesy parts and they look different. I'm not too familiar with the terminologies but are catalytic converter and catalyst converter two different things?

I listed the link for the mangnaflow CC. Please let me know if the dimensions will fit?

To replace all the cats, do I need to buy three of these? I guess front, rear and passenger?

Thanks for your help.
