Methods and systems are provided for an emission control device for an engine system including a gasoline particulate filter (GPF) and bypass passage for the GPF. In one example, the system may include a converging cone to direct exhaust flow through a central bypass passage, housing a valve, which originates upstream of the GPF and eventually passes through the center of it (thereby bypassing the GPF). In another example exhaust flow may travel through outer passages, coupled between the converging cone and GPF and spaced around the central bypass passage, to travel to the GPF.
