to those who have a 2000 up maxima without a turbo or nitros, but do have an exhaust system, y pipe cold air filter and wider diameter of exhaust pipe will ading headers in this situation increase accleration in take off or power.

 

I have an '02 Max, and I do have an exhaust system on my car. I don't really know what kind or what it really does, considering I bought the car with it already there, but I was considering making some more adjustments to compliment it. Strictly from what I have read here on the .org, for the 5.5 gens, headers are overwhelmingly recommended over a Y-pipe and will do more for your ponies, as for the 00-01, as I would draw from this implication, the Y-pipe is more beneficial than headers. However, I do not speak from experience, only the implications I have drawn from what I read, hence I could be wrong. Would be good to hear from someone who has headers on their 00-01.

 

Headers on a 00-01 Maxima gives more power over a Y-Pipe...

about 20whp, a y-pipe gives about 13whp

On an 02-03;

Headers: 21whp

Y-pipe: 8whp

 

Now this thread is over.

 

If you are asking about "Take Off" I dont think you feel headers too much for launching,low end. But trust me when I say you will notice a difference in "TOP END"

 

If you want more low end make sure you get the timing advance along with the headers. Thats what I did and it really made a big difference.

 

from what people are saying it looks like headers with a y pipe will be nice, i have a y pipe , from what i have read it seems like people are saying that an aftermarket y pipe with an after market headers is suck. my maxima is an 2000 se five speed. it is from texas not california, not california emmisions,will headers fit my car. or will the 02 sensor, ac compressor and egr valve get in the way.At the upper end with headers will it scrath the tires coming of first. it is a clutch

 

Silly question about headers.

Assuming everything else is stock, and aftermarket headers are installed, will there be much noise gained from this? How about driveability? It would nice to get a bit more power, but not at the expense of extra noise or bad driveability in the city.

 

For all the people asking "other" header related questions, they should refer to stickies at top of 5th gen forum im sure you will find an answer there.

 

Did you dyno with your headers vs. y-pipe?

I don't think I've ever actually seen a dyno of an VQ30DE-K with just intake/exhaust and headers (besides the FI guys...). Where is your information from, out of curiosity?

I thought the general consensus was that on lightly-modded 00-01's that the header gains were negligible compared to a good y-pipe since the ypipe already eliminates the precats (as opposed to the 3.5's, which saw considerably better gains with headers since the ypipe does NOT eliminate the precats)...

 

I did not dyno my HotShots, but I did see one or two 3.0's dyno them... To lazy to search... (for now)

Most of the gains from headers over a y-pipe on a 3.0 are from longer equal length primary tubes and better collectors.

If I remeber correctly, the only way all the pre-cats are removed with a y-pipe was if it was a Fed-Spec car... Not to many of them were...

 

so is it better to have a y pipe by itself, or a header by itself or both of them together

 

Read the pm I sent you...

 

if you have a vq35 you better get headers for it

 

i was under the impresion that all headers came with a y pipe since each y pipe was specific to the header...correct me if i am wrong

 

Wuts up! Would you mind answern that question for me? Because I was thinking about headers, y-pipe, straight pipe, and dual exhaust kit for my 2000 Max. Im trying to create a monster.

 

1. headers include a y-pipe, or you can just buy a y-pipe by itself.
2. "straight pipe".....Are you referring to replacement of the cat and the b-pipe with just a standard piece of piping?
3. dual exhaust....you can't do real dual exhaust (i.e. 1 exhaust coming off of each manifold) on the Maxima. All you can do is split the single exhaust into two at the rear......and all that does is add weight to the car (why would you want to...)

 

Hi!
I didnt' know headers include a y-pipe.
I believe thats what its supposed to do. It was on customenterprise stated as "Simply remove your factory catalytic converter and replace with this pipe." btw it was called a "racing straight pipe".
The dual exhaust kit, from customenterprise, stated. "The dual exhaust itself branches off from a FlowMaster Muffler which maximizes horsepower gains 8-12+ from your stock exhaust and finishes off with two 4 inch polished stainless steel tips that will give your Maxima the unique look you have been waiting for. "
I just felt that the maxima with dual exhaust was extremely sexy to me and gave it a greatly aggressive look.
I am a great fan of VIP styling, in which I want to style my Max in that fashion minus the extremely large wheelz. And the dual exhaust would help complete my look. And I would think as well as performance.

 

Its on customenterprise.com. Check it out. I value your opinion Irish. I would like to know if it would be worth it in your aspect, as well as anyone else.

 

what problems might i run into ateempting to put those headers on my car, , which headers out there have the most reasonable price with the most decent gains

 

From what i've picked up from the moderators and veterans of this forum themselves would be the cattman/hotshot headers. Enjoy

 

Word on the street is that HotShot is done...

Out of business... And I just sold my set, so good luck finding them.

All we have is Cattman now.

 

damm!

 

yes, before i buy the headers i am still atempting to find out what problems i might run into , as anybody else with a 2000 maxima se stick putt catman on your car, does the ac compressor get in the way, or egr valve or any 02 sensors, am i to believe that there is an attachment on the catmman headers to weld the egr valve on?

 

Cattman's got a new design coming soon.

 

Any idea when?

 

contact steve at sport compact only if you want some hotshot headers. $550 shipped

 

I thought HotShot was out of business and I know SCO never stocked them...

 

dont know about that.

 

Thats what Im waiting for.

 

1. the "test pipe" or "racing straight pipe" or whatever CM calls it is worthless. In fact, Soonerfan (a local buddy and org vet) had one on his first 5th gen and took it off because it actually made the car perform worse, IIRC.

2. The "dual" exhaust - if you're doing it ONLY for looks, then there's nothing wrong with it I guess. But:
- you will NOT gain any performance at all
- you're adding extra weight to the car (which hurts performance)
- you'll have to cutout the rear bumper for the other tip, unless you buy a rear tip

3. I'm not a big fan of CM parts....

If you're looking for a good exhaust setup for your car:
- Headers are an option, but a cattman y-pipe would be almost as good, and less expensive
- Get the cattman catback....It looks badass, has a nice tone, and gives real performance gains because of its straight-through design..not huge power, but maybe a couple.

4. I try not to buy car parts from anyplace that uses scantily-clad women sitting on cars as advertising. Companies that make the best stuff let the products speak for themselves, not slutty models...just my take.

 

this is COMPLETE AND TOTAL B.S. Maybe you gain 1-2hp, but I doubt that. And the extra weight will offset any tiny gains.

If that's your thing, then go for it. I personally will take performance over looks almost all the time...

 

Hey Irish thanx 4 the info. Look like customE lost a buyer. Besides the woman doesn't catch my attention. The sportier look of the dual e'd max did. I want the combination of styling, but most importantly performance. So cattman is the best we have overall?

 

you and me both josh.
