Abstract
The exhaust manifold has a plurality of individual pipes each having an inlet which is detachably connected to an exhaust gas outlet of an internal combustion engine. Each individual pipe has a catalytic converter section which makes an angle with the inlet, defines a catalytic converter axis and contains catalyst means for the catalytic treatment of the exhaust gas. In a cross-section at right angles to the catalytic converter axis, the catalyst means have a cross-sectional area which is greater than the inlet orifice area of the inlet so that the catalyst means cause only a relatively low resistance to flow when exhaust gas is passed through.
