View Full Version : Performance Header interest

In light of reliability issues with certain companies and quality issues with others along with recent fitment+quality issue with a header I got, my friend is going to make one for my car. It will be a 4-2-1 SS header. Making a few design adjustments to correct the fitment and alignment issues with one i got. (was also extremely poor welding with the one i received ie hole in the joint of #2 n #3 pipes)
R&D will be done on Hunter (my Elantra wink.gif) Taken to dyno for before and after to get honest figures. No matter what he is making one for mine, just questioning who else would want one once it clears his and mine standards. Were both Eagle scouts if that gives u any inkling wink.gif
So feedback. This is no pre-buy or anything. Simply who's interested and how much they are willing to spend for a quality product that will be sent promptly.
Couple things i wished to ask: Header is the same for the Beta II power Tiburons?
Same for 2001-2006 Elantra, any others? Ie what about Beta I vehicles?
PS: he is same one making my cat-back system with the Borla muffler i got.

I would be interested in one. I would like to see pics before I quote a price though.

I'd be willing to pay about $300-350 after it's been properly tested and works like a quality product

I would think that $400 would be about the minimum you could charge for a quality SS header.
how are you going to arrive at your design?

Explain please. Don't quite understand.

he is saying you can only get crap for under 400$, and is asking what kind of design you will be going for, since ALL of them are already available, and for less.
As for the OBX headers, buy it for 130$, re-do the welds, and it will cost you way less.

Obviously not since thats the crap i seem to have gotten! So much needs to be done that we felt it would just be easier to make a new and better quaility header.
And this thread is here because we are making it not trying to find a supplier. The OBX stuff is crap and isn't always available. Hotshot no longer makes any, and all other sites charge 350 or more and each have their own issues.
My attempt here is to look at providing a setup more readily and correctly done.
No matter what i will have a custom header for my car, simply asking if others might want to take part afterwards.

I think 350-400 is a good range. hope everything works out great becasue i'm really interested and already bored with my setup.

While I agree that 350-400 is a good price, I have some concerns.
I personally don't want a 4-2-1 designed header. I'm building my car for racing, and I need the upper power band power.
If you were going to make a 4-1 design, long-tube, stepped header, then I would be in for that.

Depends on how well things go with this one. Dyno charts will be shown. See for me i want more power down low.
BColeman

I agree, most do want the power down low, and I completely understand. I've designed a header for my car, using 3 varied stepped runners from each of the ports to a Burns collector. From my calculations, I can gain 5 hp and 3 tq. down low, with the maximum up top of about 17 hp and 14 tq. But, that's just premature calculations. Someday, when I find the right shop, I'll have my header made to what I want.

I am with you there. I would like to have the power on the top end. With the 5-speed, I have enough gear ratio to get the car rolling.

well, if you're going to develop a really kickin' header, you cant just take a shot in the dark at primary length/diameter/etc.
I guess you could:
1) ask a pro
2) use engine calc software
3) cut and try

Think we lost a couple of votes and posts here.
Friend will be using Autocad program and we will be cutting and tryin as well. But i think he has a design fairly well in his head already. It will probably a long tube 4-2-1.

Since he is in cad already, see if he is willing to design a 4-1 as well. I know that there are a few people here that would like one, myself included.
Silentwolf

I think money is an issue and he's doing this 4-2-1 for me since we are old buddies from scouts, otherwise he'd be tackling Sentras (his) or Civics(his slave :D) I'm buying the pipe bender for him as payment for header and probably exhaust as well since i already provided muffler. So it really depends on how well the header sells. 4-1 is not as popular and as such i'm not sure how he may react due to monetary constraints. As it is he's willing to eat parts and labor costs for making the 4-2-1.

Alright, here's the current lowdown. The header will be a 4-2-1 equal length longtube header made of tempered steel with choise of either ceramic or stainless steel and option of adding/welding in a cat (additional cost for the cat option)
The 4-2 section will come most of the way down the engine front, the 2-1 section will curve under and join about 6in after the curve/under the engine. The cat option will be in similar location of our stock second cat, thus second O2 sensor wires will need to be extended for header set with cat.

I know they got a bum name around here..... just plan for it to take a really long time and you'll be fine. once it shows up its a gloreous thing of beauty. welds are all tig and beautifully done. it's held up to canadian winter's without rusting better than the hotshot's ceramic coating..... only problem is you need a metric flange to mate up with it.... kinda a pain in the *** so plan to modefy an existing one or buy one from SR when ya get the header.

Cool... thanks a lot.

Sorry Folks, not going to work out. Apparently the pipe bender he had in mind was not a mandrel bender, and those are too much for me to invest in. He is also dealing with getting masters in ME so time is getting to short for him. So almost back to square one for me. :(

yeah, I knew when you said that you were going to buy the bender for him, that it wasn't going to be mandrel bent. most people would just buy the bends and weld them into the desired shape unless they were doing a large production run.

Does the efautousa header have fitment or other issues?

Well, we live and learn. Didn't really know about the differences in benders until speaking with Only1 and then seeing the bender my friend had in mind. The header we had in out heads is probably a good design and idea but my funds and his time are lacking. I do have muffler tho along with a usable cat and flex pipe from the messed up header, so in long run I'm not out anything more than just time. Just need to find a place to get a custom exhaust done up with the Borla muffler.

Never know if and when you guys have it in stock, and email response leaves a lot to be desired.

I personally havent been fond of you guys since the dyno for your exhaust produced an erroneously high result.

Well anytime people need to know if something is in stock, you could just email or call or reach us on AIM, and we even have new message boards. We havent hard hardly any email issues in months, but we still wanted to put up the message boards just in case someone couldnt get through on email.
As far as the dyno, do you mean you are punishing us because we had a great dyno result? or are you saying we fudged the numbers? Because I can assure you that wasnt the case. The place that did the dyno couldnt believe it either so they checked it multiple times. You can ask them driectly if youd like. www.pannauto.com The employees involved in that dyno were Justin and Thanh. Pann Auto is quite a well known shop in the San Diego area...the biggest of its kind south of Los angeles.

well, as you recall, I'm sure, there was quite a big argument that broke out on the forums when you published your exhaust dyno results.
I knew the results were wrong, so I went to far as to purchase the exhaust and do a before and after dyno on it, then sold it to another member at a loss.
from memory, I believe that the exhaust picked up a very respectable 8whp, though I'd have to dig out the chart to be sure.
I posted the results, and the thread slowly died...now, forever forgotten since the archives dont work.
I didn't like the can muffler of the exhaust, but the performance was great (not 20whp great, but great), and so was the craftsmanship. I've just had a bad taste in my mouth regarding evo fusion since that incident.
if it makes you feel any better, I'll probably buy your header if I decide to start modifying the elantra again.
it seems to be the best on the market in its price range.

Well again, i dont think we should be punished for posting numbers that a third party who checked and rechecked them got. Perhaps it was the perfect day, perfect car, and perfect dyno (wasnt dynojet) that got the great gains that day. But each one was consistent, the baseline dyno, the intake, the header, the exhaust, then all three together...And we paid a lot of money for all of that testing. No way would we not post up the results just because it "seemed" like our product was actually incredibly good!
Heres a question since were in a topic about headers
for the 04-06 elantra, the downpipe (flexpipe). As you guys now, we made a straight thru design eliminating all of the cats. If im not mistaken, on the 01-03, it has to be like that if we want a weldless install, because theres no flange on the cat. But on the 04-06 elantra, is there a flange on the cat?
I ask this because one of our customers for this exhaust, a company that does kia, said that on the spectras, there is a flange on the cat, so that we can actually make a shorter downpipe that attaches to that. So my question is twofold.
If we make the shorter flexpipe, would it bolt on to the 04-06 elantra? Did we make a mistake on the 01-03 elantra, and there IS a flange on there as well? Both? Neither?
Silentwolf

No. The flange is after the second cat on my 06 Elantra.
