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.

Overview
The standard Datsun 1200 exhaust manifold features a Heat Riser to deflect hot exhaust towards the bottom of the intake manifold. Since it bolts to the intake, it requires a matching Intake Manifold.
See main article: Heat Riser
GX exmani for Datsun 1200 is a divorced type -- not connected to the intake manifold
Divorced type is used with a water-heated Intake Manifold.
Heating the intake plenum is important for part-throttle performance/driveability and fuel-economy. For more information, see Heat Riser.
Single Outlet
Early A12s used a two-bolt exhaust pipe flange. A14/A15 and late A12 have three-bolt exhaust pipe flange.
2-Bolt Outlet
Datsun 1200
B110 manifold has 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.

Datsun 1000
B10 manifold look like the 1200 manifold, but the heat riser area is smooth, without the two vertical standups of the 1200 exmani.
Heat Riser flap was used starting in mid-1967.
1000 Coupe used a dual-outlet exhaust manifold (see Double-Outlet section below)
