Free Chinese Headers....

...

Power gains from the headers appears negligible as there was no 'seat of the pants' difference. Other then the headers the exhaust and engine is stock.

Being familiar with the design of these I expect a small loss of bottom end torque and a small gain at the top end of the curve (when compared to a stock M20B25 Manifold and down tube set up.... But we'll see.

Free Chinese Headers....

... included with deluxe massage.

Oh shit...

I just got that...

these are probably made by the same guys making the ebay 24v headers, which i am running on my s50 swapped car. they are loud and raspy due to the thin material used. they also let alot of heat through, which is why i wrapped them with fiberglass.

This is where you can get them for about $150....

The quality of the ones they sent are probably the very best they can do...

So I can't really say how good it is in general...

But they are a hell of a lot better than the ones I've seen go for 300 ~ 400 Plus from the e30 junk peddelers...

I was told by independant sources that the ship fast.

So give us the mothafucking dyno sheets!

Oh shit, if he wasn't to get it, I wouldn't either.

LOL

Haven't got to it yet, It'll be a while....

I can already tell you what to expect though...(think I already did..)

Be assured it's on my list of shit to do though... (long ass list...but it's on it)

[cferb]

Lol, thank you, finally someone reputable has seen them firsthand to comment on them. I always get arguments out of people when I try to say they're crap.

Nice research project. Subscribed.

Personally, I want to hear them. This is not a '75 Nova, with 50 ft/lbs and 60 WHP to be found be swapping intake and exhaust headers, so I know no real power increase is to be found in the pretty metal tubes...I just want to hear them.

Yeah, we all know "generally" what to expect from headers designed like that.

Just curious to see the actual numbers.

that's not really true, a set of well designed extractors should see a healthy gain in torque. not 50ft/lbs on an m20 of course, but a nice gain.

cheesy made in china mid length headers though? yeah, i wouldn't expect much.

These are a direct copy of the headers we used on the short tracks in the early 90's. (the "long tube" headers sold all over hell are also direct copies)

The build quality is not the same but the design is sound.

Personally I would never sell these and I don't think I'd use them on my car because I knew some of the guys that designed and built the originals...

And I hope they are still gainfully employed.

I wouldn't consider those long tubes though. mid length at best. ;)
