System Operation

3.7L Ti-VCT 

Exhaust gases pass through LH and RH catalytic converters into the exhaust Y-pipe assembly. The exhaust gases then flow through a resonator which is part of the muffler and tailpipe assembly.

3.5L GTDI 

Exhaust gases pass through the LH and RH turbochargers, catalytic converters and then into the LH and RH exhaust flexible pipes. The exhaust gases then flow through the underbody catalytic converter and a resonator which are both part of the muffler and tailpipe assembly.
