Cheap Steampipe Exhaust Manifolds

[GTS4onP]

Hey,

I'm going top mounted turbo on my car and found these cheap (chinese I'm presuming) mild steel manifolds. Anyone here had one?

What are you opinions on them?

Cheers

a well known reputable manifold is sub $1200

the 6boost one's are $1200 ish

hks ones are $1200 ish

you expect a cheap knock off @ $400

to withstand 1000deg+ EGT's

hold the weight of your turbocharger

and for it to perform?

good luck

What's the thickness of pipe, flanges???

Sinco Customs makes good quality top mount steampipe exhaust manifolds in NZ -

http://www.sincocustoms.co.nz/view-product...p%20Mount%29/16

10 year gaurantee to not to crack. Also made of 3.7mm thick steampipe that keeps heat in and exhaust velocity up and 12mm flanges that won't warp. 20-30kw gains with higher boost levels.

Yea, well we can't all afford expensive manifolds so trying to get as good as I can for my price range, just wanting something better than the chinese stainless manifolds as we all know what they're like.

Not too sure to be honest SKYPER, have asked the seller a question on the auction. How much are the Sinco ones? Don't have a great deal of money to spend on it

I would just get a chinese one and mount the turbo and exhaust correctly, if fitted correctly they often last ages. Its when they get fitted with the weight of the turbo and exhaust hanging off it that they crack

By the time one cheap manifold dies, and you replace it with another cheap one...

The decent manifold works out cheaper

All i know is the two times i have used the cheapies, both have made over 300rwkw and are still going strong 4 years later.

Apart from using a Gibson Motorsport style hanger/brace, how do you avoid the weight of a turbo hanging off the manifold?

[Adriano]

Support it partially with the exhaust. IMO it is usually the exhaust that causes the problem, imagine the force that an unhung exhaust puts on the manifold as you are bouncing along in a lowered car.

I also machine both manifold surfaces before fitting and whenever refitting if necessary.

[Dale FZ1]

Poorly hung exhaust systems will often be accompanied by vibrations so shouldn't be that hard to spot. Agreed, the type of leverage they can place on the turbo and manifold are likely to cause problems.

One thing I see as a possible plus for this particular manifold is that it's not stainless steel. Perhaps not as fatigue prone either?

It's a bit of a judgement call, but at the price point perhaps worth a second look. I do agree that the other named brands are known quantities and come ready to bolt up, not requiring extra facing or bracing, or internal finishing that costs time and/or money.

just putting it out there I reckon this would be a better option than the shiny stainless ones at the same price point

I got a reply from the guy on a different auction. 2mm thick pipe, 11.5mm thick flange, tig welded
