Exhaust System: Description and Operation

DESCRIPTION




EXHAUST SYSTEM - V6 SINGLE SYSTEM







The exhaust system consists of two front close coupled catalytic converters, a RH rear muffler and resonator assembly, and on vehicles equipped with dual exhaust, LH resonator and tailpipe assembly.





EXHAUST SYSTEM - V8 DUAL SYSTEM







Both catalytic converters attach directly to the exhaust manifold using studs and nuts. The exhaust down pipes exit the converters and connect into the rear muffler and resonator (1 and 4). On the 2.7L/3.5L equipped vehicles, there is a flex coupler directly behind the LH catalytic converter. The upstream oxygen sensors are located in each exhaust manifold. On 5.7L equipped vehicles there is a flex coupler behind both LH and RH catalytic converters. The downstream oxygen sensors are located behind the flex couplers. The 6.1L does not use flex couplers. The downstream oxygen sensors are located behind the catalytic converters.


For the single exhaust systems, the RH muffler, resonator and tailpipe (4) are one single unit.
