Is there any diffence?

 

performance wise or apearance wise?

 

actually, there is a difference. i've had a couple of threads about this. anyway, the difference is the y-pipe. the 99s have the normal 4th gen y-pipes whereas the 99.5 use the 2000 y-pipes. i know for sure my car is the 99.5

 

how do you know if your car is a 99 or a 99.5?

It's about y-pipe time

 

someone correct me if I'm wrong, but I believe SE is 99 and SE-L is 99.5

if you're not sure look for little badges just after the front wheel wheels.

KrZyMaX... what kind of y-pipe do you have?

 

I'm still waiting for Warpspeed's y-pipe to arrive in the mail. They're still not finished with the 99.5 y-pipes

 

They will be soon

 

There is no difference between a 99 and a 99.5

The difference in the Y pipe is the Federal Emissions and the Cali Emissions. A lot of 99's were produced with Cali spec Emissions. It's not a 99.5 car, it's a cali spec emissions car. That makes the Y pipe much different. Cali spec has 4 sensors in the exhaust where as federal spec only has 2. The pre cats might be different in the cali spec car as well, but I'm not 100% on that one.

 

ALSO DIDNT YOUR 99.5 SEL'S COME WITH THE TITANIUM COLORED GAUGES AND RIMS AND PERFORATED LEATHER ON LEATHER EQUIPPED CARS AND SPECIAL FLOOR MATS?

 

Yes

 

Ummm there is a difference between a 99 and a 99.5 and yes there is a 99.5 (Mine is listed with the Bank as a 99.5 and my insurance lists it as a 99.5)... It would be that all SE-L's are 99.5 and all regular SE's are 99. Some of the SE-L's like my brothers are Fed Spec and some are CA/NLEV like mine. I am not sure if all regular 99 SE's with CA/NLEV have the newer 2k-2k1 Y but all CA/NLEV 99.5's do. Any yes all 99.5 SE-L's have titanium accents, titanium SE-L badges and if you have leather they will be perforated with an embossed SE near the sholders. Please remember just because you have a SE-L does not mean you have a CA/NLEV you may have Fed spec check under your hood for the label saying that it meets California emmisions if it says federal then you do not have CA/NLEV. (unless the hood has been replaced then it could be incorrect)


If you think you have the newer CA/NLEV Y look at the front exhaust manifold you will see a huge 3" Pre-CAT directly connected to it with a heatshield around it. The fed spec version does not have the Pre-CAT directly attached to the Manifold because it is part of the Y pipe.

Look at this pic you can see the very large front Pre-CAT:

And here is a pic from below of the CA/NLEV front Pre-CAT

So for the purposes of buying a Warpspeed Y-pipe for my car (a 99 non-SE-L), it doesn't matter whether I have Fed spec of Cali spec emissions, and I just need the 99 y-pipe (not the 99.5 y-pipe), correct?

 

NO

You must tell Warpspeed you have a 99 with either California or Federal emissions. The pipes are different depending on your cars Emission Specs. SE or SE-L has nothing to do with the pipe, it's a trim level.

 

LOL, okay I'm getting confliciting information in this thread.

According to Greg's site, ALL 99 Maxima's with CA emissions require the newer 99/2000 CA Y-pipe design

So with this information, I'd need the updated "99.5/2000" CA y-pipe for my 99/CA, and not the older 95-98 CA design.

So if I have all of this correctly...

ALL 99/CA Max's require the updated 99.5/2k Y-pipe.
ALL 99/Fed Max's still use the OLD 95-98 design Y-pipe.

Is this correct?

And I still have no idea what the hell a 99.5 is. I think it's just a term that WS is using to differentiate the different Y-pipe design

If that's the case, Cattman describes it better. They have:

1995-1998 ANY SPEC y-pipe
1999-2001 CA/NLEV emissions ONLY y-pipe
1999-2001 Fed-spec emissions ONLY y-pipe

But wait, then this means that *ALL* 99's use the updated Y-pipe design and not just the CA/NLEV spec models.

WTF?!!

F*ck it. I'm just going to email them and let them tell me what the hell the differences are. I'll post up the email when I get some replies back.

 

Read that carefully again. The 99 Model has 2 Y pipes. One for Cail Emissions and one for Federal Emissions. Just tell Warpspeed which emissions your car is equipped with and you will get the correct pipe.

Who cares if the 99 shares the same Y pipe as the 2k & 2k1, Just tell them what car your driving and what emissions it's equipped with and you get the correct pipe.

Why is this so hard to understand?

Conversation I recently had with Warpspeed:

ME - Hi, I'm interested in a Y pipe for my Maxima.
Lady @ Warpspeed - OK What year is your Maxima?
ME - 1999
Lady @ Warpspeed - Do you know if you have Federal Emissions or California Emissions?
ME - I have California Emissions on my car.
Lady @ Waprspeed - OK it takes us a little longer to make that pipe for your car - do you want aluminized or SS?

bla bla bla...... Whats so difficult about that?

 

I have a 99 or 99.5 SE-L. I don't know if my gauges are titanium or not. They do sparkle a little in direct sunlight. I don't have leather so the perforation thing doesn't work for me as an indicator. I just put on my Warpspeed Y and there were only 2 O2 sensors on the Y pipes, both stock and aftermarket. What I'm gathering from the previous posts is that I have a 99.5. Is this correct?

 

This is just unreal. There is no such thing as a 99.5 Maxima.

Bluebird - you have a 1999 Maxima with Federal Emissions.

I give up! Common sense is lacking here these days.

 

If there is no such thing as a 99.5 then you should have declared that in your earlier posts. After all, the subject of this whole thread is about the differences btwn 99's and 99.5's. DaEnigma said that his is listed as a 99.5 on his insurance and I think he said it was on his title too. How do you account for that? I'm not saying that there is or isn't such a thing as a 99.5 Max, but I can't help but feel challenged when you tell me that I am lacking common sense. I posted a question in an inquisitive manner based upon the information displayed earlier in the thread. The condescending nature of your response is not appreciated. I don't want to start a peeing contest, I just wanted an answer.
Well, I'm out of here until Monday. Headed to Quaker City Raceway tonight. Hopefully I'm in the 14's! Try not to flame me too bad while I'm gone.

 

Bluebird... I share your confusion and am glad that you posted this question.

 

saying "there is no such thing as a 99.5" is not entirely correct. the whole "99.5" title is just a saying to clarify the difference in y-pipes. easiest way to end this confusion is to look at your y-pipe and see how many O2 sensors there are. it's either 2 or 3. if it's 2 then you have a regular 4th generation y-pipe. if there are 3 O2 sensors, then you have a 5th generation type y-pipe. blah.

 

Anybody have any ideas of how much HP is gained (y-pipe cali-spec) since it's leaving a pre-cat on there still..
