An aftertreatment system is disclosed. The aftertreatment system can include a hydrolysis catalyst disposed within a first canister adjacent to a downstream end of the first canister and a nozzle positioned to inject reductant into the first canister upstream of the hydrolysis catalyst. A particulate collection device, which may be catalyzed to promote NOX reduction in the presence of the reductant, can be disposed within a second canister of the aftertreatment system adjacent to an upstream end thereof. An exhaust conduit can extend from the downstream end of the first canister to the upstream end of the second canister. An interior volume within the exhaust conduit can extend from an upstream end adjacent to and in fluid communication with the hydrolysis catalyst to a downstream end adjacent to and in fluid communication with the particulate collection device.
