I know it has probably been said many times, but I have done a little searching and can't find the answer. I know a cold air intake alone is worse then the stock intake but I think I read on here that it is better then stock if you have a y pipe but I can't remember. Is this the case? If not, when does a CAI become better then stock? Thanks

 

most will say never. performance wise, that is. sounds better, but no gains. the y will give you significant gains. the intake will not really help either way. the OEM is supposedly so well made that it is hard to get improvements over it unless you were to force air in, ie: FI.

i would suggest just the y-pipe and perhaps a cone filter if you want a little more growl.

 

Get the y-pipe and call it a day, there will be 1234721985X10e^10 opinions on this ... So take anything with a grain of salt, but until someone provides dyno results that the CAI is better than a y-pipe,

 

i know a CAI isnt better then a y pipe im just wondering if a cold air intake would be better with a y pipe then by itself. Cause Im getting a budget y pipe and wondering if I should get a CAI to go along with it.

 

Well, the rest is history, but I'd go with CAI lower and stock upper (resonator)...

 

yeah, keep the resonator and uh...take it one step at a time. you dont need to buy them at the same time. you will feel the y pipe without the CAI.

 

Just my 2 cents, but it's interesting to me that soooooo many people say there aren't any performance gains to be realized when using a CAI/Popcharger/etc. A Stillen popcharger was the first modification I ever installed on my '97 and the difference was substantial (read: it didn't simply sound better). I experienced faster, smoother acceleration throughout. Recently, I installed a 2.5" exhaust from the manifolds back and picked up quite a few more hp. Just for fun, after reading all of these posts claiming that the stock box is better, I reinstalled mine. The car was significantly less powerful immediately. I installed the Stillen intake again and...vroooooooom! Is it just me or my car or...?

 

is it F4 or F6 that shows your dyno?

 

I had a cone filter on and I took it off 1 week after I got my y pipe.

 

Why can't someone just dyno this damn thing and finally solve the mystery. Let's all chip in... I'll donate $1 to the fund.

 

I never said that... As the fastest Maximas have some sort of intake(non-stock).

The stock box is said to be better for smoothness/everyday/calm/around town driving.

Everyone else throws it out of whack, when we should all be putting more energy toward something more interesting because intake threads are , and shouldn;t be dwelled upon. I'm here (in this thread) because I'm bored.

 

According to the Stillen catalog:
(Stage 1- Hi/flow CAI = 6hp),
(Stage 2-Cat back = 8-12hp),
(Stage 3-Underdrive pulley = 8hp),
(Stage 4-Ignition upgrade = 4hp),
(Stage 5- Y-pipe= 10-20hp),
(Stage 6-Flywheel = 6hp),
(Stage 7-cams = 13-15hp),
(Stage 8-supercharger = 80hp), and
(Stage 9-honed intake = 10hp).................For a grand total of
190hp (stock) + 6 hp + 8-12hp + 8hp + 4hp + 10-20hp + 6hp + 13-15hp + 80hp + 10 hp = 335-351whp

 

I hope you're not serious


math

*edit Didnt see the stage 8 S/C

 

But you can not use stage 8 and stage 5 together if you have an auto car?????

 

Don't ever read the stillen catalog and believe it.

 

Well I know the styling kit has to be worth like 200 hp why didn't they list that
I was really just throwing some number out there to compare, but most of the numbers do make since<-(my spelling is really bad).
350 whp what a BEAST!!!!!!!!!that would be!!!!

 

You forgot to note that buying a Stillen product automatically makes how much bhp you have the amount of whp you have.

 

It's called the Stillen Conversion Factor.

 

holy crap. way OT. end thread. just stick with the stock airbox for overall 'best' intake. of course, do whatever you want, though.

 

CAI=Auditiory horsepower

 

Guys as a newbie, I am reading through all the great info that you all post out here, and after reading this thread I wanted to validate whether a Y pipe gives gains without any intake mods, and are intake mods that beneficial?

I know the whole breathe better concept but with all of the electronics on the fuel injection, I was just curious if the intake mods are valuable.

Thanks

Nate

 

intake = sound
Y-pipe = power

intake+Y-pipe= powerful sound....+power

dont ask any more questions. thats how it is.

 

lol i love it.

Thing is we have dynos to prove y-pipes work. But we dont have dynos of just an intake. Since we dont have a dyno of an intake you can assume that we dont have a dyno of a CAI with and without a Y-pipe since thats what your asking in particular. You can be the first to give us the baselines of everything.
In order to prove you point we would need A.baseline run B.CAI run C.run with just a y-pipe D. Run with both Y-pipe and CAI installed.


4 dyno runs to prove your point and finally put an end to this madness.

there.

 

^^^WTF that doesnt change anything....wheres the stock airbox graph??? Hmmm???

 

I picked up a warpspeed y-pipe about 2 months ago. I got a 96 max with 201,000 miles. I installed the intake months before the y-pipe and didn't notice much of a gain if any but it made it a hell of a lot louder. As for the y-pipe, when I first installed it I didn't notice a gain at all. But then again I never reset my ECU. The next day I drove down to FL from NY without getting on it. I guess the ECU read it by then cause when I got on it down there and had a civic try to race me, I sure as hell noticed a difference. Definately worth the $200.

 

not to hijack this thread or anything but unfortunately im a newb and i cant send pm's..Kormax97 where did u buy that skyline rear bumper from??...

 

Umm... we all know a y-pipe gives you gains.

 

no **** sherlock. it provides a look into the dyno of a pop-charger alone, as well as with a y pipe.

cool smiley though. ****in sped.

 

also, just how important is it to reset the ECU after installing the y-pipe?

 

I never have after any mod

 

Sped huh? Haven't heard that since the 6th grade. Good goin buddy. Did you not read what I said? That dyno is completely irrelevant anyway to this thread... idiot.

 

it should reset by itself after a hundred or two miles.

 

if he had a stock we could of compared it to stock VS stillen cone intake. but we didn't so yea like all the guys said. it doesn't help at all. Resetting the ECU is something that CAN be done but isn't needed. Your ECU will detect that your exhaust gases are flowing more smoothly and stronger and it will do its adjustments on its own.

If you reset the ECU all you doing is making the ECU learn the new AF mixtures and other things. Its really pointless.
