I know after this question, I’ll probably get voted off the island.

But I searched and I believe I have the answer. I just wish someone could prove me wrong. A ’99 Cali Spec Y pipe will not fit a ’97 Cali Spec Maxima. Any ideas on what would be required to make this work and an approximate cost. Would it be cheaper to just get a Fed-Spec Y pipe and replace all parts to make this work? (Cali to Fed conversion)

 

It won't work. Just buy a '97 Y-pipe.

 

i really dont understand the question but i have a 97 y pipe on my 97 cali car and now have a 99 cali motor and everything still bolts up. the only difference is 02 sensors i believe.

 

your 1997 is NOT cali spec.

 

I do believe it is!

My Twelfth character is a V.

But I sure do wish I was a Fed-Spec

 

then you better tell nissan they dont know what there talking about because they said it is. and explain the million 02 sensors and cali spec computer and anyway your wrong.

 

i could have sworn that ONLY 99's had cali spec

 

me too and i was pissed off because i have so many sensors. also i was told the car came with stock lsd which was read from my vin #which has a V in it.
wether thats true or not doesn't matter anyway because i have the stillen V TEK lsd

 

if your front manifold has a pre cat in it then a 99 cali Y will fit.... but as far as every one knows the 95-98 maximas only have one y pipe. you would be the first to have a 99 style 97.

you have an engine bay pic?

 

95-99 had Calispec, but only 99cali spec had different ypipes.

 

thank you. ive seen 97 cali cars before

 

You've pretty much answered my question,

 

I thought I pretty much answered your question in post number two.

 

He explained it better
