Altima has a different Ypipe. Also the subframe is totally different on a Altima vs our Maximas. You can't use Altima headers on a Maxima- unless its a 6th gen.

02+ Altima is pretty much a 04+ Maxima.

We have a crossmember on our 4-5th gens, 6th+ gen has a big subframe/cradle under the car with no crossmember. Hence why the Ypipe is different.

 

Ok thanks. Thats what I was wondering.

 

I'm not really to fond of spending $800 on cattman headers. Where can I find obx or hotshot. Ive tried ebay, classifieds on here and on nycmaximas.org. and also craigslist.

 

you didn't search on ebay..

OBX: http://cgi.ebay.com/ebaymotors/OBX-9...QQcmdZViewItem

Hotshot:
http://www.2kracing.com/index.php/cPath/532_536

just heads up....shouldn't have posted here..classified would be the place to look...and post for this sort of info

 

If you have a 2000 Max, you can't really use HotShot even if you found a set since they have no EGR port.

As for OBX, you get what you pay for IMO.

Go Cattman or don't bother.

 

since I cant start my own thread yet..i'm asking anyone who knows enough about the VQ35 engine and the tranny is it possible to do a full swap into a 03 altima without having to buy tranny..?

 

hence the rule.. . .

 

Still not answering my question

 

Ask in the correct place and there will at least be an attempt at an answer.

 

Does anyone know how the SFR headers are overall in generall compared to other headers such as cattman or hotshot?

^^^ I'm not sure but those things are over a $1000. So why bother when $859 is a load for Maxima headers.

 

Uhhh, not going to work... They are for their custom turbo system.

 

SFR actually made the Cattman Gen II headers, which are of good quality.

 

I thought Brian stopped the Gen II because of inconsistent quality...

 

Okay, maybe true, so let me rephrase. MINE are of good quality.

 

going on tomorrow...woot!

If you see closely theres an egr valve on the header. Even though my car is an 03, Brian said it just wouldnt be used but rather when Im ready to sell, I can expand my selling base to not only 02-03 maximas, but 95-03 since they use the EGR.

 

I have been running the hotshot's for a while and have developed a header leak. Any advice on what gaskets I should purchase to fix this problem? Thanks

 

Where is the leak? If it's at the engine, just re-use the OEM triple layers. If it's anywhere else, you can stop by any auto store for some gaskets... it's more about how you tighten them (alternate, etc,...)

 

I reused the OEM gaskets, as advised on the forum. The leak is coming from the front set i believe. It is at the engine.

 

I had a leak about two weeks ago, but it was because I used the crappy supplied gaskets. What I think is best for you to do is to remove the front exhaust manifolds and remove the gasket so you can scrape and clean the surface on the engine. This will remove all the grime that might've been building up 'til now. Give that a shot.

 

I tried all this stuff and none of it works for long. Just run the secondaries back to to B pipe.
I'm going to see if I can flash the ECU to do the job.
More later.

 

Explain your problem a little further.

 

will 4th gen fed spec front side headers fit 5th gen? Will the cattman y pipe line up?

 

If i go to a custom exhaust shop, cant i just replace the precats with regular exhaust piping? I figure the CE light will go on but does anyone think performance will be affected? i mean i hear its the precats that really kill performance in the whole exhaust.

 

Here's the deal. I've searched and just can't find that this question has been addressed. My 2002 SE exhaust is rusty and will need to replace the entire exhaust in the next year. I want performance, but want to avoid an embarrasing exhaust note when when the family and I are picking up my mother for mothers day, eh? So here are my priorities

1. Near stock sound, throaty OK, but no rasp.
2. I want to avoid SES lights, so all cats need to be there, but I have no problem having threaded bungs added.
3. Must fit with the Blehmco LTB II
4. Performance

I'm thinking headers to the exhaust tip, but if headers reap little reward, why buy? Maybe replace just Y pipe back. I've done headers on two prior rides.

Please respond with your solutions to this issue. Mixed manufacturer parts lists are OK, but I'd prefer to drop my cash on one manufacturer who has an established reputation. I want to know they are likely to be there if I need to replace something. No fly-by-nights please.


I very much look forward to people's opinions in response to my quest, but first-hand experience is much preferred to second-hand. Hear-say is not worthy of a response.

Thank you in advance for your help.

 

cattman..........

 

I am finally having a shop install the headers that have been collecting dust in my room for six months and they are running into problems. Please help!

they say the headers are missing the rear 02 bungs and would have to have them welded on, and something about the wiring having to be too close to the axle which isn't safe...I had them explain it several times but it was kinda confusing. Does anyone have some pics of cattman headers installed in their 02 max that I could show them? They are also worried about fitment issues.

This is the only pic of the headers I have since they didn't have a digital camera there at the time. Can anyone look at these and tell if they should fit my 02 max se?

Thanks

Ryan

 

Those are the correct headers and there are no rear O2 bungs. You have to either weld the bungs into your b-pipe and extend your O2 sensor wiring for the sensors to reach or just use an O2 sim to get rid of the CEL.

The information and links to threads with details are in the first post of this thread under Oxygen Sensors.

 

thanks!

 

I did purchase and supply the o2 sim to the shop installing the headers but the guy said that normally the o2 sim's don't work very well and he recommended hard wiring it up.

Does anyone have some detailed instructions I can give him to try and use the o2 sim, or instructions on how to hardwire it in? And can you hard wire it up, not use the o2 sim, and not have to have the new bungs welded on?

I managed to lose my installation instructions, and Brian from Cattman is out all this week for the holidays. Thanks in advance for any help guys...I reaaallly appreciate it. Also, if you've installed them yourself before I could have the guy installing them call you and ask a few questions if that would be easier than writing something up for me.

the link is in the 1st post....

 

Thank you, I managed to miss that when search through this post

In case he cannot do that for some reason, is it possible to wire it up without using the o2 sim and also without having to weld on new bungs?

///EDIT///

Oh ya, and if anyone has some undercar pics of their cattman headers installed can you please post them? My mechanic was holding the catback piece under the car and said the angles were quite a bit different than the stock piping and said he thought it may not fit. I know it must fit though! It has to! I've waited too long to get these installed to not have it work lol =)


Ryan

 

he needs to keep both the front and rear manifolds lose to line up the y pipe, if he tightens up the front and rear and then does the y it wont fit...

 

You can always leave the secondaries disconnected and live with a CEL. i.e. there is no way to not use an O2 sim or bung the secondaries behind the main cat, and not have a CEL. What seems to be the problem?

The O2 sim install is the one of the easiest things to do on this car. Use the O2 sim and leave the secondaries plugged into the harnesses and call it a day. I've had the O2 sim for 3 years and have been code free. For what it's worth, I've also passed two VA state emissions inspections.

Like said above, keep things loose, connect everything, and then slowly tighten component by component.

What sort of catback do you have?

Anyway, here's a picture of mine if it'll help:

 

THANK YOU SO MUCH GUYS!!! =)

I think this information will help, going to send it all to him. I'll keep ya updated if I get it installed correctly.

 

i have been reading the thread for a couple of days now. in one of the post it said the the 4th gens and the 5th gen have the same y pipe i think. so i have a guestion will most 95-99 header systems fit a de-k 01?

if this is a stupid question or it has already been answered then i appologize in advance.

 

so this has been bothering me very much does my 2001 se have and egr system or no? i have been looking in different forums and everyone seems to has a different answer. so i would like to know.

 

A little late to reply, but someone gave me an idea a very long time ago and just wondering if anyone thinks this will work. What would happen if someone with a 5.5 gen bought 3 liter OEM exhaust manifolds and a 3.0 y-pipe. I have a feeling it would probably fit, and would give comparable gains to the 3 liter y-pipe swap. Or am I way off?

 

where can i find cheap headers for an 02 maxima?

 

ebay.. or check the 5th gen classifieds from time to time
