Exhaust manifold

Apparently ss gets a little more brittle with each heat cycleing and most of the cheepie ex manifolds are made with thin wall tube material and can usually be identified by little reinforceing?? tags at the runners to head flange.
That said there are ss manifolds available from the US that have lifetime guarantees to the original purchaser and with our $ having parity with the USD now would be the time to buy if funds are available
They would be app the same price as a 6BOOST m/fold if Kyle would make them

Steam pipe is perfect for manifolds. I think it lasts longer then mild steel and stainless

Correct me if im wrong but i thought steampipe WAS mild steel.

Im getting my manifold made next week so will chuck a few pics up when its done.

how many manifolds have you ever had to replace because they rusted out?

Cast manifolds seem to stand the test of time in terms of being affected by rust, but then cracking is common. Mild steel exhausts don't fare that well because they rust.

You gotta use something though.
Type, grade & thickness are all important factors.

Yes it is, but I was more talking about the higher grade steam pipe. I had a normal mild steel manifold that rusted and fell to bits inside of 2 years. My new steampipe manifold has lasted so far 3-4 years and doesn't even look like its going to rust.

The stainless on the ebay manifold is 2mm thick.

which is too thin...

steampipe is the go for exhaust manifolds, and MIG welding. unless you can find someone to TIG who will actually put enough heat into it to get good penetration!

Now im really worried. I thought that was alot of metal. Where can I find a decent manifold?

6Boost (who hangs around a lot of different forums) does top quality work, but it'll be about $1000 from him, maybe more. Mind you, the end product will justify the cost.

Quick Spool at Cleveland 32625224
Redzone at the Sunny Coast
GT performance at Newmarket they made Kit's ss mani
Gonzos Exhausts made Starion VR4's mani
Exotic exhaust at Sumner Park
Expect to pay close to 1k for a top class tig welded manifold

There is also Luke from Turboshop on the Gold Coast. He makes some quality work as well:
