Does anyone know what our manifold is made out of, and can it be welded?

they look like cast iron to me. plenty of guys have welding to it making turbo kits of out factory manifolds.

Cast iron.

The surface rust on ours gives it away!

Well crap. I had some joker the other day telling me they was cast stainless.
There's no way I'm going to try and weld on cast iron. You know 4 door grocery getter and all. The wife would be pissed if something let loose under there while she was driving.
Not to mention the Vin Diesel jokes if the welds on the manifold cracked. Lol

u can weld on these manifolds just make sure you do a good surface prep. BTW wtf is cast stainless?

You can weld them or have them welded.
BUT , they have to go to someone who is familiar with cast iron. And they need be on a torquing plate throughout the welding process.

I thought they could be welded, but I don't want my first time to be on the GXP. And I'm kinda weird about letting other men but their hands on my baby.

Hell if I know?

Just as it sounds. Cast manifolds but instead of using cast iron, they use Stainless Steel. Durability of a cast manifold without having to worry about rusting. I ran a set of cast stainless tru-rams on the SBC in my fiero.

Here is a set for the LS1:
