An exhaust treatment system is provided for treatment of an exhaust stream, where the system comprises a first dosage device, arranged to supply a first additive into said exhaust stream and a first reduction catalyst device, arranged downstream for reduction of nitrogen oxides in said exhaust stream through the use of said first additive, and for the generation of heat through at least one exothermal reaction with said exhaust stream. A particulate filter arranged downstream of said first reduction catalyst device to catch soot particles. A second dosage device arranged downstream of said particulate filter to supply a second additive into said exhaust stream and a second reduction catalyst device, arranged downstream of said second dosage device for reduction of nitrogen oxides in said exhaust stream through the use of at least one of said first and said second additive.
