Well I took a chance and had these powder coated. I had one done in black and tried something new with the other.
This one is coated "chrome". Now I know it does not look exactly like chrome but it does look a fair bit like non-polished aluminum which is what I was shooting for. If you have any experience with ceramic coated headers that's what it looks like in person.
It was very bright when I took these pictures outside.
This inside picture shows it's shine better.
I will post up some pictures of the black one tomorrow. It can be seen a little in the last picture.
