A catalytic converter having a pair of catalytic converter members disposed in a housing. A pair of catalytic converter members is disposed within the housing along a longitudinal axis of the housing. A annular structure is disposed within the housing between the pair of catalytic converter members, such annular structure having a hollow inner region disposed along the longitudinal axis to enable exhaust gases introduced into the housing to pass from a frontal one of the pair of catalytic converter members, though the hollow region of the annular structure, to a rearward one of the pair of catalytic converter members. The annular structure terminates at a front edge and rear edge. The front edge engages a rear, outer peripheral portion of the frontal one of pair of catalytic converter members and the rear edge engages a frontal, outer peripheral portion of the rearward one of the pair of catalytic converter members.
