I want to get a budget Y for my 99.5 fed spec 5spd. When I go to order it from Budget I jsut need the 95-99 fed spec right? Or is the 99.5 special in anyway, and if so, then what do I do. Thanks for the help! Cant wait till I get this slapped on the max!

 

99.5 is different. The guy at budget refused to believe me. Greg at cattman emailed me a diagram showing how it was different. That's why I got the Cattman. 99.5-00 have the same one. I think the Cattman part# is CG5.

 

1995-98 model year maximas...fed spec y-pipe only.
99-01 model year maximas....fed and cali spec y-pipes.

Being a 99 or a 99.5 year maxima does not make a difference as far as this subject is concerned.

 

I ordered a Budget 95-99 y-pipe for my 99 SE-L fed spec...is it going to fit???

And what is different from the 99 fed spec y-pipe and the 99.5 fed spec y-pipe?????????????????

 

Ok, i just visited cattman's, warpspeed's and stillen's websites and yes they do have a different one for 95-99 and 99.5's. But on Stillen they had a different one for 99's and 99's that had a production date of 3/99 or later. These would be the 99.5's right? My SE-L's production date was January of 99 (1/99) so my car would be a regular 99 even tho it's an SE-L?

 

Yes it does. The year 99 has two different emission systems.

A year 1999 is a fed spec vehicle
The model year 99.5 is a California has the California spec emission system on it. And the differences in the two car is more then the Y pipe. There are also changes in our ECU's and intake manifold. We have swish valves in our intakes as well.

As far as the Y pipes go, are cars are marked as 99 and 99.5 for the reason that 99.5 emissions and our ECU's are completely different then any other 4th generation Maxima. A 99.5 ECU will not work in a 99 and vice-vers.

 

Well then, do I have a 99.5 even though its an SE-L?? I have FED spec emessions, not Cali. I have it marked on the VIN plate and I see only 2 sensors in teh front of the car where there would be 4 if it was Cali emissions. What the heck do i do?

 

Hmm...I sit and type corrected. Thanks for the clarification Tom.

 

99.5 y cali spec pipes donent have one of the tubes goign up to the exhaust manifold.. so one precat has to stay for the ecu to work. it think cause its obd2. not 100% sure on this.. someone correct me if im wrong..

the stillin y is universal b/c its 2 peice.. u can remove of of the pipes that goes up to the header to fit a cali spec, or have both pipes that go up for a fed spec.

 

SE-L doesn't mean your a 99.5. Your emissions will designate you 99 or 99.5.

Being your a fed spec means your a 99.

 

Sweet, so my Budget FED spec y-pipe will work for my 99 SE-L (production date 1/99) right?

 

just look at the front of your engine. if you have 4 sensors you are cali spec. All of the Cali Spec cars for 99 were SE-L's

 

Thanks, so make me 100% sure on this, I can go ahead and get the 95-99 budget pipe from them then right?

 

Redmax, that cant be because I have an SE-L and I dont have Cali emmisions, I have 2 sensors and in the decoding of the VIN# thats here on the .org somewhere, I have Fed spec too.

 

Your right. SE-L - The Limited is a trim level. Has nothing to do with which emissions your car has. There are SE-L's with and without Cali Spec emissions.

So the only thing that follows is Cali Spec = 99.5 and Fed spec is 99.

Jr. - Just order the basic Y pipe from them. It should bolt right on as long as you only have 2 connectors up front. (only 2 O2's in your factory Y)

 

IF your 99 has a production date of March 1999 or later, it is a 99.5.

My 99 SE-L was built January 1999 and it IS a fed spec.

 

So where is the 4th O2 sensor?

The way I understand it is this...the fed spec car has two O2 sensors, one that plugs into each down pipe portion of the y-pipe. The CA spec car has 4 sensors...the two I just mentioned plus one on the front pre-cat and one which is....??

 

This is the Cali spec y-pipe. for 99.5's



This is the Fed spec for 95-99 models and is the version Budget sells.


Simple thing to do is just look at your factory pipe and see which one it looks like.

 

Your exactly right, What i said was all cali specs are SE-L's you wont find a 99 cali spec that is not an se-l.

 

Yes you will.... We've been through this before on this board. There out there.... 99 SE's with Cali Spec Emissions and no Limited Trim package. They identify that car with it's 99.5 model year.

Might be hard to find them try the search feature, there have been discussions regarding this in the past. We've seen every combo of Fed, Cali, SE and SE-L trim packages.
