I just got off the phone with Dallas at WarpSpeedPerformance and within the next two weeks I'm heading up there to be the very first 'test monkey' for the 2002 Maxima Y-pipe. Yipppeeee!!!! Heres the scoop.....

He said that the primary problem was that one of the flanges is different on the 2002 model than earlier 4th and 5th gens. I asked him about estimated gains, and he said that while it wouldn't be the 18-20whp gains the 4th gen guys see, it would be at least in the area of 15whp. We talked for a good while and discussed what exactly is gonna happen. He said that essentially I come in and they try to fit the prototype and adjust/tweak it as necessary. Once it is fitted to my car, I can pretty much drive home. That way the computer will have time to relearn and adjust. Once I get home I'll get the post dyno results (they'll dyno it before hand BTW) and post them as well as send him a copy.

Now in our conversation he did say that he would appreciate it if you guys did NOT flood him with e-mails saying, 'whey will it be ready'. As soon as the correct specs are taken from my car, it should only be a matter of a couple of weeks before mass production starts. Prices will be the same as the 4th gen Y-pipe.

This is it guys....its finally here!!! I'm so excited! Please me respectful of his wishes and dont flood him with calls or e-mails since he did ask me to mention that specifically. Also, can we get a head count of 2K2 guys who are ready to buy one....NOW WITH MONEY IN HAND? Not, well, if I had some money, but only those that could buy today.

 

Great News!!

Assuming great fit and finish (proper placement of all o2 sensors, etc.) I would buy.

Brian

 

Yeah, he said that the only quirks with the 2K2 pipe are different flanges. He said that hopefully the adjustments shouldn't take more than a few hours.

 

Well if everything goes well and no problems occur, then I'm in! I hope its before the month or else the $$$ will be gone

 

How much will it run again? ($$-wise) Btw, Maximus... weren't you the one who wanted to sell his 2k2 just recently? What up?

 

Yeah, I did. Its a love/hate relationship.....but now its all love..lol. I think it was somewhere around $250.00 or so.

 

Good to see you let the love shine through

$250? I figure installation costs wouldn't be that much more... pretty good price. I'll check back when it's finally out. Thanks!

 

I will read tonight, but can you give me an idea of what it would take to install it? Do I have to be a mechanic, or is *limited* mechanical ability enough to do it on my own?

 

I really dont have the space/tools to do my own install, but I imagine if you have jack stands, a torque wrench, and some elbow grease it shouldn't be too hard.

 

That is all you need, get a a swivel head attachment too, it will get to the hard places. Maximus you could do it, trust me!!!

 

I probably could, but since they are fitting it for me, I'll just sit back and take notes.

 

if it fits ok i'm already in now i have money in hand can't wait

 

You along with at least ten other people that I know of.

I'm so excited about this now. For the money, this will be such a great mod for the 3.5L. With Injen CAI, UR pulley, Y-pipe, and maybe WSP B-pipe with stock muffler (still considering the B-pipe though) I whould be pushing 240 or so to the wheels and who knows how much torque.

 

I can't wait for the Warpspeed vs Stillen vs Cattman comparo.

 

Well, that may be some time to come since the Stillen Y-pipe has been '30 days away' for the past six months.... Has Cattman even announced intentions to make one for the 2K2?

 

Oh yeah, while I'm there I'll be getting the Stage II sfcs as well. Whew, the anticipation is killing me here.

 

Both Dallas and I can't wait as well. Considering the both of our competitors use a 2 1/4 collector and we use 2 1/2. We get higher flow. Looking forward to independent, unbiased testing.

Dan WSP

 

I'm looking forward to meeting you guys. I need to hold on to my crown as the fastest 2K2 out there.

 

Does WSP make a Y-pipe for the 2K1 and 2K2's? Sorry if that's a stupid question but I have read so much about Y's over the last 6 months I am confused.

 

I'm not sure. I know Cattman and Stillen do. Cattman has had some severe quality control issues lately (i.e. flex section).

 

I'm ready to buy....money in hand!

 

I know there are more than two people who would be ready to buy tomorrow....c'mon now. I guess more people will check in as it gets later.

 

i think people are just waiting to see what happens. i'd like to tell you i'd buy one tomorrow but my decision would depend on price, proven gains, and how the y-pipe holds up.

 

Thats why your humble servant is here to help you.......

*evil though* dyno gains near 20whp and realize that I could tell them that it is horrible and stuff so they have to redesign, meantime, I'm the only 2K2 out there with said Y-pipe. Hmmm....

Just kidding.

 

You've been unseated! SR20DEN is running a 160 shot of nitrous already! hehehe..

But yeah, this money's been burning a hole in my pocket for the last three months while I've been waiting for this. How bout a y-pipe already I would buy tomorrow.

 

Oh yeah, forgot about that. Has he run at the track yet? Mine is allergic to the secret sauce if you know what I mean.

 

It's ok, I'm going for the N/A route for a while too for some reason I don't feel comfortable pumping my brand new engine full of happy juice just yet. You still hold the record for bolt-ons!

I think he's taking it down to the track in a couple weeks, should be exiting.

 

This kinda blows.. I just ordered a 2000 Y-pipe from them to jerry rig onto my car. I wish Dan or Dallas where actually available to speak to so I could avoided this pickle pickle, ohh well, atleast Dallas called me back ( I misseed him though). Well with this new info I am probably going to try to return my pipe and then just eat the shipping costs.



Ohh yes, you guys are going to have a little trouble getting this to work too. You most likely need to relocate 2 o2 sensors behind or in the main cat, other wise the car will shoot a code and run funny. This may be a big problem for the regular joe smo.

 

Hey Emax, I sent you an PM about getting you involved too.

 

Well, as long as they fit PROPERLY, Im in for sure ! One more step in becoming the fastest 2K2 Auto on the ORG... ! Now lets move on to headers and cams !

 

Did Dallas really say that 4th gens dyno 20fwhp with their Y-pipes? The highest I've personally seen on a all stock auto 4th gen with their y-pipe made 11fwhp over stock. A 5 speed with an intake and their y-pipe made an extra 13fwhp. I've never heard of a 4th gen gaining anymore than 14fwhp with any make of y-pipe. With the 2k2 y-pipe, I doubt you'll see much more than a 5-8fwhp gain. The design is already much better than the 95-01 design. I could be wrong though. Do you have a baseline to compare to?


Dave

 

My car was never dynoed stock unfortunately. By the time I get the Y-pipe I'll have the Injen CAI and UR pulleys (not to mention lighter wheels).

I did talk with him at some length about whp gains. He said that Stillen inflates their number to something like 28whp which is outrageous. He clearly did say that he has seen close to 20whp on 4th gens. I'm not sure if that was with an intake as well or just stock. Ofcourse we are going to dyno mine there before installation and than dyno again after install and 200 miles or so for the computer to learn.

 

I remember one 4th gen guy dynoed and got a 16 FWHP gain with a WSP Y-pipe.


Max1000, I will write back to you in a sec.

 

Some thoughts:

Emax: I think you should go ahead with your manifold conversion+y-pipe. You stand to gain something out of it, especially if O2 sensor relocation is necessary regardless. As someone previously stated, if the precats really are in the stock manifold, then a y-pipe would only yield better flow post manifold, and the primary restriction of the pre-cats would still remain.

Dan/Dallas:
Perhaps you guy should consider using a 2.75 inch collector and pipe diameter after the y-joint. Especially since the VQ35DE is signifigantly larger in displacement than the VQ30DE and most likely has an increased volume of exhaust flow per pulse.

Kloogy: Cams are on the way! SR20DEN had commented previously, that the VQ35DE has an optimal timing advance of 4 or 5 degrees more than stock. This could be part of nissan's way of detuning our engine so that we would be 2nd to the Z. This means a few things, one of which is that we have much to gain from ignition timing. (this has nothing to do with cams so far btw.) Secondly, if cam profiles from the 350Z and G35 coupe are more aggressive than ours then we can look forward to being able to swap these out for our own. Unfortunately, I'm sure that buying 4 OEM cams from a dealership would be rediculously expensive. Nismo and the aftermarket, however are sure to follow with aftermarket cams for the VQ35.

Anyway, my goal of 300hp to the crank naturally aspirated looks to be attainable

 

I agree Chinkzilla , without NOS !

 

Heres a pic of the 2002 headers conecting to the precats.



As you can see the precats bolt right onto the manifolds. I think I am going to stick with my game plan though since connected a Y-pipe to this manifold would be a litle hard to make flow smooth (I may be wrong). I am going to relocate my o2 sensors in the next few days to prepair form my Y-pipe arrival.

About the cams, this has me very excited! How hard would it be to install new cams? Does the engine have to come out or what?

 

Veetec got 16 fwhp with only a cattman y-pipe.

 

Yeah, and his had like 128K miles on it. I wonder what a newer engine would have gotten.

 

I have my money in hand for the new Y-pipe and will purchase contigent on two things.
A) Verification that the pipe fits and fits without fabrication and without excessive or intrusive noises. B) Dyno results.

Just waiting on those two and you can chalk me down.

Jesse

 

I'll take pics of the install and get a copy of my before dyno. I'll redyno in Little Rock of the post Y-pipe results. I'll post those immediately following the dyno.
