Where are o2 sensors located on 99 Cali Specs?
I had the car jacked up while installing new suspension and i noticed that i didnt have any o2 sensors after my cat. I have a test pipe and aftermarket catback so i figured the only way the only way i passed my inspection was because i still have factory ypipe. Now my question is, are all the o2 sensors located on the factory ypipe? If I removed the factory ypipe for an aftermarket, will it be impossible to pass inspections? Ive read the o2 simulators only work for sensors after the cat.

Here is more than enough information about the 99 CA/NLEV Maxima exhaust and no there is not an O2 behind the main Cat...
This pic only shows the three O2 sensors which are directly connected to what is called the y-pipe and the cats:

There is also another O2 sensor above the front precat in the actual manifold (the one with the blue wire) pictured here:

hate to redig an old thread but when i put in the 5 speed fed spec ecu i can just unplug the two o2 sensors that are after the cat and i guess the two i keep are the ones right after the heads ? btw im putting in a fed spec warpspeed pipe.....
and to double chek the only parts for the cali to fed swap is the y pipe, lower intake and cpu ?
