I did some searching and I am unable to find the answer to my question, which is one that I'm sure has been asked over and over again. Here it goes....

I have a 2000 maxima and I am about to buy a warpspeed y pipe, it asks me if I am cali spec or fed spec. How can I tell?

Again...I tried searching, and found some links to some "definitive" threads but they do not work so I am sol. Also, my haynes manual does not tell me.

 

Fed spec has three O2 sensors.
Cali spec has four O2 sensors.

If you have a Fed spec car, you'll see two O2 sensor connectors in front of the valve cover, and one by the rear coilpacks.

If you have a Cali spec car, you'll see three O2 connectors up front.

 

I just took this pic, are these what you're talking about, because if so there are 4 of these things right in front of my vc. You said there are only supposed to be 2 for fed spec and 3 for cali so which is mine since it has 4...

 

the right side is not an O2 sensor. i think it's a sensor for the tranny, but not sure. the rest of it is O2 sensors. the last sensor is located behind the intake manifold, close to the fire wall

 

so cali spec then...

 

i was wondering the same thing and i only have 2 connectors, so i guess mine is a fed spec

 

yeah it appears so

 

Last one closest to the right is the VSS connector I believe.

Correct

 

If u look at ur Y pipe they are different..... cali spec y ___l________.... fed spec l___l______
