Beschreibung
Zusammenfassung:	An exhaust assembly for a vehicle includes an exhaust pipe through which an exhaust gas flows substantially in a first direction. The exhaust pipe includes a central region. The assembly also includes a sensor in fluid communication with the exhaust pipe and an elongated tube extending from a first end toward a second end and disposed at least partially within the exhaust pipe. The first end of the tube receives at least a portion of the sensor. The tube includes an inlet opening and an outlet opening. The inlet opening generally faces the exhaust gas flowing within the central region in the first direction so that some of the exhaust gas flowing in the central region enters the inlet opening. The tube directs the exhaust gas within the tube toward the sensor, and the exhaust gas within the tube flows out of the tube through the outlet opening.
