someone have tried those ??

the price is so low... ok maybee they are not good for 300hp but for a dealy driver that have a value of 2000$ ??

i'm not sure if a brand new warpspeed would be a good choice

fitment is always a guess on these cheapy egay headers. better off with a warpspeed.

ACee

I have them on my 2003.

I have those headers on my '97 3.5 swap.
Not bad.

Warp-y though.

I've had many bad experiences with cheap headers

Post some pictures of them and what kind of issue you may have had with fitment if any? I don't care if fitment is an issue that way I have a chop saw and Fab skills!

well if anything the Y-Pipe alone is worth it LOL

Since I have an 03, I had to add 2 o2 bungs for the upstream sensors and I used the non-foulers for my 2 downstreams.

The hardest part for me was the removal of the rear heat shield. I ended up taking the valve cover off to get it out and just went ahead and replaced valve covers and gaskets when I was in there. I can try to take some photos if you want but there were already some on here.

As far as fitment. I ended up removing the three (six total) bolts that came in the actual header and tack welding in grade 8 bolts that I bought at autozone. The nuts and bolts supplied with my set couldn't hold the torque that I put on them so I put the grade 8s in their place.

If you replace the bolts, then make sure to get fine threaded grade 8 with nuts to match.

I too would be interested in pictures of the headers from the engine bay and below if possible.
Ive got an 03 Maxima and cant see myself throwing down the cash for even just the obx headers for my model. So naturally these seem like the best option for me.

I may just try these on my 97. Since I need a whole new exhausted anyway and the only local options would be some crappy crushed bent system. Surly this cheap eBay system would offer better numbers over a stock exhaust. I'll be sure to post if I do try them.

IMO, you're asking for a potential headache going for these. These headers probably won't give you any gains over stock, only the ypipe will due to the removal of the precats. With that said, just go for a reputable y-pipe like Warpspeed or Cattman.

I'm guessing this is the same for an 02?

max ride 41

iTrader: (4)

thank you, unless cattman or better, warpspeed is better for added hp.

ACee

I can get you some photos but you might need to give me a day or two.

I have actually been debating on trying the obx headers because they are longer individual tubes. Just spending the money, you know?

Not sure the quality of bolts or the o2 bung locations on the obx....

But I am prepared to relocate the bungs and remove and install adequate bolts if needed.

Let me see what photos I can get for you.

You got a dyno to back it up?

One question for me on the obx is how do you fit the rear bank header up from below? Because it is welded to the y pipe and I only see installing from the top.

TexasTex

iTrader: (1)

I'd like to see that too. Not questioning it, just curious.

ACee

Me too.

I have yet to see anything but hearsay.

Yes.

TexasTex

iTrader: (1)

I figured, but it seems there's always a slight change, somewhere from year to year.

ACee

Too many photos to post.

Start here and go through my photo bucket...

If you select the other album within photo bucket there are more photos.

It took a while to learn the installation process, but I could do it now in about 3-5 hours. Including removal of old and not including drilling out broken studs or modifying the headers that are supposed to bolt right in.

you can't see hearsay

that's great if you have a garage and a tool bench and wan't to spend all that time for little to no gain. i've been perfectly happy with the warspeed y, eliminated the pre-cats and felt a nice little jump. i'm not going to dyno a mostly stock max, i can bet it's a 10- to 15 hp gain. not much, but the stock headers are good enough for me.

ACee

If my stock precats wouldn't have taken a dump on me and not to mention these were all that were available at the time, then I would have kept it stock or maybe purchased something else.

And little to no gain is still hearsay.

If a y was made for my o3 that would have eliminated my precats, then I would have went with the y.

TexasTex

iTrader: (1)

You can when it's typed out.

iTrader: (4)

not, it's hearsay so it doesn't exist and can't be proven in a court of maxima.org

i never been around the headers but i thought the headers are mounted on studs (stock)?

Fakie J Farkerton

iTrader: (51)

Threads come through the y, no studs at the top.

Set of headers I had did not have flat flanges so one bank had an exhaust leak..

TexasTex

iTrader: (1)

Wow, that's BS.

ACee

Actually, I think stock is called exhaust manifolds and aftermarket are called headers.

Climaxx

iTrader: (4)

exhaust manifolds = headers
headers = exhaust manifolds

potato-puhtawto. lol

TexasTex

iTrader: (1)

Agreed.

6cyl-97maxima

I'm sure your correct, but here is how I am looking at it. Warpspeed y-pipe is apx. $200+ Canadian and that's all you get, well flex pipe too. This is apx. $160 Canadian and not only do you get the y-pipe but you get headers and all required gaskets. If there is fititment issues with the headers then I just simply wouldn't install them. Either way I would still be getting the y-pipe for less than a warpspeed one. Quality control would not be as good but as far as gains, y-pipe to y-pipe, IMHO, there shouldn't be a whole lot of difference between the two, (generic VRS. Warpspeed), since as you stated its the eliminated pre-cats that give you the real gains.

The Wizard

iTrader: (43)

You're making a big assumption that if you don't use the headers, that the y-pipe will bolt up no problem. I'd bet money that it won't work.

schmellyfart

iTrader: (46)

Correct.

I had a set of cheap eBay shorties 4 years ago, only installed the y pipe and the y pipe flanges were a good 1/2" or so off from the stock exhaust manifolds.

ACee

What do you have installed now?

DJ_Nismo

it say on the item description:
Each Set is Tested and Dynoed to Make Sure the Fitment and Performance to Meet our Goal
Direct Bolt-On Installation

with 98.2% Positive feedback

I buy it now and will update with pics soon

I already have a custom 2.5inch catback, the Y pipe is 2.25 so I will need something to correct this but I don't think it's a big issue..

My main issue is my wallet lol

Well, I hope this doesn't turn into a case of a penny wise and a pound foolish.... Good luck! and keep us posted.
