Manifold repairs - what's possible, not possible?

[S Works]

Morning all. Say I had a cracked manifold, the crack being in one of the pipes on the 4 part of a 4-2-1, would it be possible to repair rather than replace?

It's a custom made jobbie from Simpson race exhausts from what I recall.

In this day and age of chuck away and replace, it pains me to see a good piece of kit thrown when only one section has a small failure, so I'd rather get it repaired if possible.

Cheers,
SW

Stevie, thanks for the info, I wanted to get some opinions from people who know better than I (not difficult, I'm a mech-numptie!) before I called anyone. I pretty much figured it could be repaired. Unfortunately I can't take pix of it as it's not on the car at the moment, but your advice helps. Thanks.

whats the manifold made off ????

He said he reckoned it was a customs Simpson racing item, tubular design, so it will likely be stainless.

Either way, repairs should be straight forward.

Yep, as far as I know, that's the spec.

Right, so if I read these correctly, welding it up is going to be a bit of a hit-n-miss affair. BUT if the offending tube was removed, and a brand new one put on in it's place, that would be possible, right?
