Catalytic Converter: Description and Operation

DESCRIPTION




The close coupled, three-way catalytic converter inlets are connected to the exhaust manifolds by the use of ball flange (1). The 2.7L and 3.5L RWD vehicles incorporate a flex joint downstream of the LH catalytic converter to improve NVH. The 5.7L equipped RWD vehicles incorporate a flex joint downstream of the LH and RH catalytic converters. The 6.1L equipped RWD vehicles do use a flex joint downstream of the LH and RH catalytic converters. The left (4) and right (2) side converter outlet pipe connects to the exhaust system.
