Headers....

BAC5.2 · Post by **BAC5.2** » Tue Oct 05, 2004 4:54 am

I'm looking around, trying to find some prices for headers.

The GPMoto headers are sweet, but at $1G, they are WAY out of the price range.

The Borla headers are an option, at $500.

Just trying to figure out where else to look. I've tried:

www.racecompengineering.com

www.gruppe-s.com

www.boxer4racing.com

www.rallispec.com

www.mauromotorsports.com

www.ninosautoaccessories.com

And no one really has much of a selection. Anyone have any other ideas?

Hell, even links to e-bay auctions I might not have noticed.

Just looking for some Equal Length headers for a decent price, and trying to get an idea of where to look.

equal length headers make it sound kinda honda-ish. but nasioc is a good resource, anything pops up on there once in a while

I've heard conflicting things about the header deal.

Some people say it makes it sound "big". I think it was Nico that said his car sounds like a huge V8.

There is a performance advantage with equal length headers, so that is what makes me kinda lean towards them. I'll check it out and see if I can listen to some other peoples cars.

I have this header, I bought it from Nate @ss-ms.com Thats s-squared if you havent heard of him. I was very pleased with it. its polished stainless and the welds are impecable. I paid 500 with tax. Very nice and my engine is very loud at WOT with the factory exhaust and factory DP

So it's an equal length header? Hmm...

Does it collect into one pipe, then split? Hard to see in the picture.

I like the GPMoto headers because they are seperate pipes until they collect, then they join. Seems like that would be the best idea to smooth flow.

it is a 4 into 1, all four collect at a large flange then the large OD uppipe goes up to the turbo. Dont look at the engine pic look at the photo in the link above the pic, you can see it better there.

Ahh, better.

I dig that. That might be the way I'll go if CES doesn't get back to me soon.

My car is going to be a SCREAMER.

1 question: One guy says tripple gasketing was required to fill a gap? Can you confirm that?

magicmike · Post by **magicmike** » Wed Oct 06, 2004 1:31 am

well I was waiting for that.......actually I'm not too sure. I put my vf34 in at the same time and I did require a spacer but it was so that the compressor side of the turbo wouldn't hit the block.

pic is a little blurry but you get the idea...

Ah-ha. I gotcha.

Well, doesn't seem like a big deal.

when you work for a machine company its not a big deal. took me about an hour to make that, on the clock might I add

How much did you end up paying for those headers mike? Do you think they actually helped out torque? Most reports I've read have said that they felt that headers might have hurt torque a little, but I don't know if that's true or not. Also, how is the sound with equal leangth headers? Do you loose the subaru burble at all?

nate eh? did he make those himself or just distributing them?

my headers gave me 2MPH at the drags, as for sounding like a V8 - you do realise masturbation makes you blind!?......

headers will make you exhaust note sound raspy and more metallic, i had unequal length headers on my RS and it still had the boxer note but sounded more like a racecar.

in my opinion worth the money....

phil, who says the gpmoto header is $1,000
this is the same header I have on my sti I was telling you about.
I sell them for $700.00.
they are very nice. one piece with uppipe. I love the sound with my stromung 3 in turboback (which I also sell)

they were talking equal length

Just wodering, but does any header for the EJ20 fit the EJ22T? Thanks

There is still speculation as to whether an equal length header on a turbo car is worth it.

The most significant advantage is that the exhaust pulses are spaced well to provide good flow out of the engine and into the turbo. Possibly promoting quicker spool.

HOWEVER,

The length of an equal length header increases the heat lost through the header, possibly slowing down the exhaust gas, causing a decrease in efficiency. This can be solved at least a little by a ceramic coating...

BUT,

An equal length header is only efficient in spacing the exhaust pulses for a given rpm. Meaning that at say 4000rpm, the exhaust pulses are spaced well for maximum efficiency, but at 5000rpm, the exhaust pulses are again just=off.

Is it worth the price? I would have to say no, for any of the headers available. I would put that money into something a little more proven to yield good results across the rpm range. Like injectors and a standalone.

Anybody seen these:

Sorry if they've already been mentioned but I didn't see anything about them when I scanned through this post. They've been selling them on ebay for quite a while. They typically go for under $350.

Either those pics have been mirrored or those headers are serioulsy screwed. The up pipe goes up the passenger side of the car and the pipes cross over the front of the oil pan. Looking at those pics the up pipe would go up the drivers side....Just my keen eye at work. I know I should have gone into detective work

azn2nr · Post by **azn2nr** » Tue Oct 19, 2004 5:16 am

they go up on the corect side remember the cross pipe is in front but its the three bungs and his feedback are what im woried about.

Nigel · Post by **Nigel** » Tue Oct 19, 2004 11:54 am

Not to defend the guy because I've never bought from him, nor do I know anybody that has, but he's had close to 10,000 transactions in the last year, and only about 1% got negative feedback. Mind you, he does seem to be a bit of a prick when replying to negative feedback.

What worries you about about the three bungs?

ok so it was late and I was looking at the pics a little funny. Never the less the bungs dont concern me but the diameter of the up pipe being the same as each of the other pipes concerns me

free5ty1e · Post by **free5ty1e** » Sat Feb 12, 2005 3:57 pm

I'm curious as to whether or not headers would actually help our cars or not - arent the insanely small pipes we have coming from each cylinder to the turbo that way so that the exhaust pulse velocity will be insanely high and spin the hell out of the turbo when exiting to the exhaust pipe?

Equal-length headers are for non-turbo vehicles, IMHO. They are for optimizing unrestricted exhaust flow. A turbo's a hell of a restriction in the exhaust path.

Some larger unequal headers might help but my main question is, won't the larger diameter piping actually make it harder to spool the turbo? Is there a tradeoff between turbine size and header size that has to be considered here...?

Basically, what I'm asking is:
Pre-turbo exhaust = better pressurized?
post-turbo exhaust = better free-flowing?

...or am I way off again? (it happens... lol)
