An exhaust gas after treatment system includes a catalytic converter arrangement with at least one catalytic material, wherein the catalytic converter arrangement is arranged in an exhaust gas path downstream of a combustion engine, and further includes one or more dosing interfaces for feeding at least one reducing agent for reducing an NOcontent in the exhaust gas. The one or more dosing interfaces are arranged to feed at least one activator material to the exhaust gas. The activator material causes an enhancement of a catalytic activity of the catalytic material compared to the catalytic activity of the catalytic material without the presence of the activator material at least in a given temperature range.
