I've no experience with the N/A engine but when I refurbished my turbo I found the exhaust manifold was cracked, particularly on the inside at the collector. I replaced it with a very good second hand one. It might be one of the reasons why the turbo exhaust manifold was changed in 1999.
I wouldn't recommend trying JB weld or similar as it will possibly very quickly fall out and if it's for cracks on the inside of the manifold if it falls out it will head straight to the Cat where it might cause damage.
I would additionally consider the condition of the engine mounts - if they are worn then you might have quite a bit of engine movement in excess of what the flexibility of the exhaust system can absorb?
Worst case scenario I think you can get new manifolds for the N/A engines from PFV if you can't find a good used one.
