Should I worry about....?

[JUDGENINJA]

Whilst making things shiny I had a closer look at the stupidly designed Exhaust manifold...It's not the most efficient of items is it....?
A big could do better mark I think was given to the designers on this one....

Anyway that's not the reason for the post as I can't weld (yet) so I'm very unlikely to make a new one, What I've been looking at is the crack in the manifold ..........

Should I worry about it.......?

Doesn't look too good to me mate i would get it sorted while its all off!

The crack hasn't gone though the outer casing, but it does look a bit odd....

Don't like the look of that at all. It looks like it's gone quite a long way from the photos. I'd be trawling scrap yards if I were you.
