I have a 02 maxima with 220k miles an the catalytic converter needs to be replaced. So I'm thinking about buying a set of headers instead. Because I think it will get rid of my cats that way not really sure exactly.

Any help would be greatly appreciated!!!

 

Well Cattman is supposedly coming back

Or you can try OBX headers

 

Supposedly...

 

Let us see who out of those who supposedly wanted to buy headers will actually buy

 

I'm broke, no headers for me! Wouldn't mind a cat-back though...

 

do it! all the cool kids are doing it.

 

Dont do it George got headers then ran into a back of a truck

 

 

Hillbilly redneck brake checked me

 

How did you brake check yourself?? no you was clearly speeding,Following unsafe distance,Using a cell phone and smoking pot at the same time its clearly seen in the video.

 

So Im gonna go with the obx headers. I can't wait an see if cattman comes back.

Will I need to do any tuning once the headers are on? I'm not really sure seems like it mine run rich tho.

 

Yes

 

It's recommended but car will still work fine

 

Feel free to explain I've been in a similar situation...

 

From what I've heard recently, those too are on back order.

 

Header are pretty much "plug and play", no tuning necessary but you will throw codes. An O2 simulator is recommended to pass many state emissions/safety requirements. To get max performance you will need a tune.

Also be conscious of the cost- most shops will give you an 8 hour estimate (which is complete BS) or you can go through the pain of installing them yourself.

Finally, be sure to use the OEM gaskets. All-in-all, even with OBX, you're gonna spend some cash, but the gains were well worth it if you ask me.

 

Yeah I'm gonna use a local shop I use a lot they are going to only charge me 3 hours labor. An we don't have emmissions in my town so no worries there. But I will need to find someone to tune it After I get them installed.

 

Get a SAFC and tune yourself.

It is cheap and opens up great opportunity for even greater gains. (larger intake/injectors/etc). But all that will begin to cost more and more. Depending on how much gains you are after.

 

What exactly is a SAFC I'm new to this. This is my first maxima I've always liked these 5th gens tho.

And I have a turbo im wanting to put on it later down the riad

Why not save up for a Gen 5.7 swap ?

 

I've actually looked into it. Maybe one day after this motor quits.

Any recommendations on headers bolts??

 

Can't you reuse the bolts or do you mean rod bolts? You need to take the engine out for that supposedly due to how cramped the engine bay is

 

No I'm buying headers an new exhaust for my car. Been looking for Stage 8 locking fasteners but haven't found anything for the 3.5s so just asking for opinions on other bolts for the headers so I don't reuse the factory bolts off the manifolds. I hear they tend to back out over time an cause exhaust leaks.

 

Loctite?

 

Look up the (Rob Ford headers) better than cattman.....?Contact george_ he's the middle man...

 

Nope...

 

Lmao! I've heard those headers have a crack problem.

 

Cattman's not coming back! Unless we get a post reply or thread from Cattman himself don't believe the Hype!!!! As for this Header thread this same title has been nearly recreated a million times....

 

 

Nissan doesn't have a problem with exhaust manifold nuts loosening like domestics did B4 MLS gaskets....if you want "peace of mind" just order new exhaust manifold nuts....

 

Post a link to this if you're for real! Then I'll post a link of D!ck Porsche headers for Nissan Maxima(s)....
