sup all
Did u know the 2000 max has aftermarket headers......Just found out tonite. check it out: www.midnightms.com Now da question!! I have da CAI and cattman Y and exhaust if I get da headers how much more hp am i looking at?? Trying to decide if its actually worth it or not..

 

looks interesting, but I beleive I will wait for more info on those.

 

Well if you look at the description, I think it says 12-14hp. Little bit on the expensive side, but very tempting.

 

Holy crap I might buy these headers. I thought this was untrue. But if they say they make it then I just might buy it, seems expensive, but for a 14hp gain it is worth it. Plus I got every perf mod besides a supercharger.

Damn anyone know why they made one? And none of the veteren max forum guys aint say anything?

Emax had headers on his previous max or i30.
I don't remember him saying that they are worth it or not.
Emax any thoughts?

 

Funny thing is I can't seem to find the header for the max on the OBX's website.

yea these headers popped up in the group deal section too

ditto on the not finding anything on the obx site

 

The headers I got deffinatly were not worth it.

I wonder if these headers include the Y-pIpe or not

 

Was this on your 95? And what exactly do you mean they were not worth it? Proved Zero HP gain? Headers almost always give you 10-15hp gain. Just wondering why. I mean they cant be made in too many different ways.

How do you guys figure that $449 is expensive ... a V6 has two headers ... you will NEVER find the cheap prices that the I4 pay. The Cougar headers are $600 and that is considered a bargain because the only other header maker Sean Hyland Motorsports headers are equal length long tube headers and cost $1200!!! I can't believe that most of you are willing to spend $25K+ on the car and snub your nose at sub $500 headers ... makes no sense to me!

 

I don't think it's a matter of exactly how much it is but rather a case of Price/performance ratio's.

IMHO of course.

 

Ask emax95 about headers hp vs. y-pipe hp.

The headers replace everything from the exhaust manifolds to the main cat.

 

if these headers are for real, then maybe we have a viable option. the new zealand headers were shown to gain only 1-2 hp over an aftermarket ypipe i believe, thus making most people who already had the ypipe say it was worth the cost. however, for someone who hasn't done a ypipe swap it might have abeen worth it. now these headers say 12-15 hp gains, while most people generally assume the ypipes add 10-12, so it looks like it might the same situation. it would seem the exhaust mainfold isn't that restrictive, but for someone who wanted to max out their car, the extra flow could be useful. Different strokes fer different folks.

 

Wait Wait Wait, so you telling me on my Cali Spec car I have to replace the manifold, cali-spec down pipe, and the ypipe? All this for $449? That seems very cheap. Not to mention I would be eliminating every precat.

Can I get a serious answer on why on a 2000-2001 there is not a gain?

Dixit

 

I'm betting misprint though.


Dixit,

The stock headers are pretty large considering the engines displacement. One example, besides Emax95 1-2hp gain, is when Phil, aka DesertPearl, swapped in 1-FED spec. header to replace 1-CALI header/precat. He didn't notice much gains either, but until the two dyno charts are laid on top of each other, you will not see the LO/MID rpm gains(read USEABLE gains).

Removing BOTH precats is probably going to show up more in LO/MID range RPMs than PEAK hp. Plus, you are "balancing" the exhaust flow by eliminating the other precat that a Y-pipe leaves behind while hopefully using equal length runners, which is beneficial to the long term life of the engine.

Somebody call them already and dyno BEFORE/AFTER!

 

That's cheap for a V6....

CL-S = $1200 ouch!

 

I wonder if these headers will fit the 2002? Any ideas?

 

The headers will actually replace everything from your exhaust manifolds back to the cat (including the manifolds). Yes, at $449 the price is VERY good.

Downfalls... you need to trick the O2 on the front pre-cat and the installation is a MAJOR pain.

Alex answered your questions on the gains of the y-pipe. Nissan exhaust manifolds are very efficient.

 

Yeah, but the Comptech headers have very significant dyno-proven gains. I don't think that's too much for 25-30fwhp.

 

Kev,

That's what I originally thought, but Dixit's car is NOT getting O2-sensor MILs with his Cattman Y-pipe and NO main cat? Do you think that last remaining pre-cat is keeping the ECU from flipping out?


BTW, SC/NOS Maximas SHOULD benefit more from headers than us N/A guys, so order one already.

 

hmmmmm...
if you can get this to work on your maxima i will give you mad props...



that site looks like a scam to me...
no address...no phone number...JUST PAYPAL ME!!

 

Do you know for sure? They could just be the extractors that bolt onto the oem Y-Pipe.


BigDogJonx, the NZ Headers AND Y-pipe gave me a peak HP gain of 2.9 over stock headers and Y-Pipe. The NZ headers flat out sucked! A Y-Pipe would have given me much better gains at 1/2 the cost. This is not to say that the OBX headers would not add a good amount of power. I would try them out but I was allready the test animal and I spilled out over a grand for a lousy freaking 2.9 HP! To top it all off the headers sounded down right horrible

 

This is some new store here in Mississippi and I don't know anything about them. I will look into this more, if I were ya'll I would not buy it yet. I am going to the coast for a show this weekend and I will go by this place and see what they are really about and then I will post what they say about these so called "headers"!

Sounds like a plan!
