Abstract
A vehicle exhaust system for allowing passage of exhaust gasses therethrough. The vehicle exhaust system has a first pipe having a first end and a second end. The first end defines an exhaust gas inlet and the second end defines an exhaust gas outlet. The vehicle exhaust system also has a second pipe positioned downstream of the first pipe and has a third end and a fourth end. At least a portion of the second end of first pipe is positioned within the third end of the second pipe defining an overlap between the second end of the first pipe and the third end of the second pipe. The first pipe and the second pipe together define a volume for the exhaust gasses. The volume comprises a first volume passageway between the exhaust gas inlet and the exhaust gas outlet and a second volume passageway defined by the overlap of the second pipe and the first pipe and having an inlet for exhaust gasses into the second volume passageway and an outlet from the second volume passageway positioned axially upstream of inlet. The inlet is positioned downstream of the exhaust gas outlet
