Exhaust Manifold

[Thuppu]

How much £££ is a exhaust like that?

+1

I see the Swedish manifold (Furans, CP-service)makers combines the tubes at the collector in ignition order (1-2-4-5-3), these mani's don't, is there any gain from combining the tubes in ignition order? A bit off topic maybe but..

[Costash]

I already ask about price and is 800 and something +vat!

[G60Rallye]

The one I posted pictures of cost me a lot less than that!

[Jamo]

It is at 90 degrees to the turbo flange yes, like the manifold at the top of the page and from the pictures about the same as Repo's. Nortech will make them anyway you want so its not an issue.

I need phone James he hasnt answered my emails

There is no benefit in joining the runners in a specific order. There is however a benefit of having them all equal length for smoother spool up. As that way the gas feed is constant rather than sometimes more sometimes less like on uneven runners.

Anyone know how much the Nortech header's are? The item isn't listed in theor website.

Nortech number: 01709888170

They can also get hold of top quality exhaust tubing and bends.

WOW, that Nortech item is a truly a work of art!! Some lovely TIG work, really nice.

Going to look at the pic's again.

@G60Rallye

What should one expect regarding price? What material is it?

[cooperquattro]

nortech in rotherham??

[G60Rallye]

They are in Rotherham yes. Manifold is 304, but they will make them with any material you like. Price you will have to speak to them, but its less than the manifold from the US.

less than which EM from USA?

If your going to get them to make you a manifold My choice of material would be 321.
Most people make manifolds out of 304 but there is several advantages of using
321, 321 is alloyed with titanium for high temp stabilisation, the titanium bonds very strongly to the carbon even at very high temperatures and this eliminates carbide precipitation and thus keeps the chromium where it should be and prevents intergranular corrosion.

304 is not as fatigue resistant at high temps and the only real benefit I can see is that it is cheaper than 321, but if your manifold is going to fail quicker made with 304 then in my opinion it is false economy .

Of course if your really flush you could have it made from Inconel.
