Cracked Exhaust Manifold GT-40

[bski]

I have a 2000 SN with a GT-40 engine. It looks like there is a crack in the starboard exhaust manifold which is causing a slight water leak (approx ten drips per minute). Is there anything I should be aware of before I replace the manifold? Would you replace both sides, even though the port side does not show any indications of wear or leaking?

Thanks!

They run 175 a piece, I would do both. I have a 96 sport gt-40 and replaced both at ten years. The longer you wait the more it will cost if your bolts get to rusted and you cant get them out.

I've got the original manifolds on my 78 martinique 351. They came off with no issues when I put gt40p heads and an intake on it recently.

Thanks for the thoughts. I’m going to order the parts for both sides. Hopefully I can make it through the summer and swap them out during the off season.
