Just picked up a 2010 XLT SCrew, and I absolutely love it. I was checking out the motor yesterday when I noticed that it looks like the exhaust manifolds both look like they have a layer of rust on them. They're rough to the touch and brown. Is this normal? How do everyone else's look?

 

Its normal, they are cast iron headers.

 

High heat, plus moisture equal rust. I know it's not very humid in FL Nothing to worry about.

 

Thanks a lot guys. This is the first new vehicle I've ever owned, excluding my wife's car. I figured it was normal, especially since they are cast iron, but I just wanted to make sure. My other car is a 1976 CJ-7 jeep, and I have the headers on that covered in fiberglass heat wrap so I never see them.
