Used Twin Turbo Exhaust Manifolds for all '90+ Nissan 300zx Twin Turbo models.

Bolt directly to the cylinder head, the turbo charger attaches to the exhaust manifold and is feed the hot exhaust gases through the manifold.  Over time corrosion and heat cycling can fatigue the exhaust manifold and leak to cracks and/or exhaust leaks.

If you are building a Twin Turbo conversion, a good used set of exhaust manifolds is an economical alternative to much more expensive aftermarket turbo exhaust manifolds on the market.
