Datsun 1200 uses a single-outlet cast-iron exhaust manifold. It has a two-bolt flange to the exhaust piping. They can be replaced with tubular headers.

Single Outlet
Early A12s used a two-bolt exhaust pipe flange. A14/A15 and late A12 have three-bolt exhaust pipe flange.
Datsun 1200
Datsun 1200 manifold with heat riser for bottom of intake manifold.
- 3-bolt stove gasket
- Datsun 1000 manifold is similar, but with a smaller 30mm outlet. A12 engine has 34mm outlet. Also the exhaust pipe joint is reshaped for performance increase.

B10 manifold look like the larger 1200 manifold, but the heat riser area is smooth, without the two vertical standups of the 1200 exmani.
