Is this premature rust?

[Shimmy Bang Bang]

Build date of August 2014. I had the truck for 2 1/2 months.

 

Is this normal...?

Looks like they got flipped around when uploading, sorry about that.

Are you talking about the exhaust manifolds? If so, those always look like that (unless you get Stainless Headers).

[Dropsix]

Yup, that's normal.

[Shimmy Bang Bang]

Thanks guys. Phew. I was a tad worried. I didn't remember seeing that before.

 

Appreciate it.

These sure are nice to look at when you open the hood, still shiny after 100K miles since install.

I think every vehicle I have owned, the cast iron exhaust manifolds have looked like that.

I posted a thread awhile back with the same question, haha

[Rewillia]

normal. cast iron attracts moisture as it cools and its only surface rust.

[Spurshot]

No, that's definitely mature rust.

 

Since the exhaust manifolds are bare cast iron, they'll rust before you ever see the truck. Nearly every vehicle on the road looks like that. If a guy was totally anal and set on no rust on the exhaust manifolds, you could remove them, powder blast and have them flame (plasma) sprayed or plated with a protective material. But It's just not worth it. Some guys want headers anyway. I'm over that. (leaks, more difficult maintenance, more heat in the compartment, etc, etc..)
