A particulate trap has a housing with an inlet and an outlet. The particulate trap also has a plurality of fluidly isolated filters stacked within the housing, between the inlet and the outlet. The stacked plurality of filters have a stack direction and a transverse direction and the flow of exhaust is directed through the plurality of filters in the transverse direction. The particulate trap further has an actuator with a blocking portion configured for linear movement to selectively block exhaust flow through each of the plurality of filters.
