Exhaust manifold help

[Brassmonkey]

Are there any stock cast iron exhaust manifolds still available? I have a cracked, right side, exhaust manifold. Or what is the best way to repair a cracked cast iron exhaust manifold? Can it be welded or patched with a compound/sealant? Any help would be appreciated.

If it's just a crack, and not split entirely open, you can have them welded.
Make sure you get a shop that knows how to do cast iron properly.

You can have it arc welded with Nickel rod or a new hybrid rod with other alloys. I often MIG weld cracked manifolds on cars out here and have not seen the welded portion break again. But cracks in different areas. In short just a bad manifold.
The stock manifolds seems to be decent material.

X2....and you will want to have it bolted to a head when they weld it. Just reinstalled mine from bein welded and I had some trouble getting it on. I ended up having to slot the aft holes just a lil to make it work. So, make sure it's bolted to a head, or a jig when they weld it.
