An internal combustion engine exhaust gas recirculation system. A turbine section of a turbocharger is coupled to an exhaust manifold of the engine. A compressor section has an output coupled to an intake manifold of the engine. The exhaust gas aftertreatment system is coupled to an output of the turbine section. The exhaust gas aftertreatment system includes a particulate filter having: a housing of an outer wall and an inner wall; a particulate filtering section disposed within the inner wall of the housing; and a channel formed between the inner wall and the outer wall. The channel created by the outer wall includes: an inlet disposed downstream of the filtering section for receiving a portion of exhaust gasses exiting the filtering section, and an outlet coupled to the input of the compressor section of the turbine for transporting the exhaust gasses received by the inlet of the channel to an input of the compressor section.
