Found them on a vendor's website

http://intensepower.com/poshtutuheun.html

Just wondering if anyone owns them or knows anything about them. I've searched and searched and could not find anything.

The long tube design looks different than the megan ones i think, even the shorty looks different than other designs. Am I rite?

 

interesting..

 

Don't know but had I the option in 2004 to go with long headers, I would have went long. Eliminates potential leak and stress points of test pipe or catalytic converter.

 

i have a set going on my car in my build, black ceramic coated, they look very nice. had em in my hand.

Are you FI?

I cant imagine ANY header helping an NA car.. im only doing it for high PSI FI.

 

nicee. how are the quality of the welds? i wonder how the fitment is.

 

When did these come out????

Brian????

 

i think i have the first set, they had been sitting in Hans office when i mentioned it.. assume theyd help w 40-50 hp at the PSI ill be shooting down the pipes..especially w my XO2 exhaust and rev y pipe for now. ( Im leaving it until its proven to be something i dont want.. for right now.. igives a Fuh about the XO2 haha. )

They looked pretty cool to be honest.. a nice scroll to them as well. Welds are always top notch... enugg where i saw em and said.. "hmm.. what are those headers over there for? No kidding? think theyd help? Ok well ill take em.. add em to the list".

 

Hmm, pretty cool actually.

 

Smh

 

Nope, I'm not FI and really have no plans to go FI neither. Just came across these the other day while surfing and found them. I just always thought there's the cheap one (megan) and the expensive one (sasha's) when it comes to long tube headers. Searched the forum and came up empty, so thats why I asked if anyone out there have these and see if anyone can comment on them.

The vendor is on our forum rite? think they know anything? dyno on an NA car? on a FI car?

 

IMO,all headers are a waste of money(a pain to install)unless a component of a major FI
build.To illustrate my point.when the 350 first came out,one of the mags(don't remember
which one)did a "tuner mod" article of a stock Z vs.one that had tuner bolt ons.They had the typical list of parts/labor costs etc.For all the big bucks shown,I was expecting
some great results.
Not so...
The results shown(hp)were in no way worth the expense.
Bottom line,Nissan did a pretty good job on the original engineering of the Z.
The aftermarket guyswent to work and in alot of cases told a pretty good "story".
One example is the OEM air box.You can improve by dropping in a K&N.But how
many Popchargers have been sold?

 

Things are different now than "when the Z first came out".

You're completely disregarding the very impressive gains that SGM was able to pull out. PPE and FI have shown the same type of results on the 370, and the few results we've seen so far on the 350/G35 -- from independent testers -- is very promising.

Also, can't expect much without a tune. The stock ECU can only adjust so much.

Edit: Also, regarding "I can't imagine ANY header helping an N/A car"...

Wow.

 

do you have any clearer pics than the one of their website ?

thx

 

was the modded car tuned in that comparison? i ask because i have bolt ons and more and have yet to be tuned, but at wot im at 16+ air fuel ratios, so a tune will add a lot to my power.

 

The SGM car has huge cams and huge long tube headers as well as non-practical intake mods. None of which 99% of the NA cars will have.

at $1000, i doubt there will be much interest in the longtubes, esp when you get 99% of the gains with 325$ OBX LT.

 

if your car is RevUp you can get solid gains w/o aftermarket cams. if you're non-rev then you'll need cams to make it worthwhile.

 

They had another car (a roadster) that was stock, except for their full exhaust system.

 

I will post pictures of the actual headers i bought next week when im down there again, cool? i have them ceramic coated tho, not sure at all what the site offers for sale tho.

and as for the wow coment for headers helping out on any NA car... as in any NA 350z. Sorry, they dont do much.. just the way it is. No where near what they will change when they are fed 26psi.
The only part of that which is purely opinion based is the " helping" part.
For a guy who is not FI, id never buy them, and so i didnt.
Now i have changed directions, so hence the headers are on the plate now.

It still remains poor advice to tell an NA guy to buy headers for a reasonable increase.. unless you have lots of other stuff going on under the hood, its just not cost effective, and for the most part, its not that Nissan did a great job designing the OEM stuff, its that the engine doesnt push things past the limits the OEM manifolds will flow and affect.

 

so got a chance to take some pics of those headers? is it similar to the PPE headers?

 

sorry man, i snapped you a few pics, but they are alrady installed.. thank fawking GOD to be honest.. this has been a rough year of waiting.

Dount these help in the least, but at least you can see what kind of space around them youre looking at etc..
