Exhaust System

OVERVIEW

5.0L V8 NATURALLY ASPIRATED AND SUPERCHARGER - FROM 2010MY
The exhaust system fitted to models with the 5.0L V8 engines are fabricated from stainless steel. 5 separate assemblies make up the complete system.
The front section comprises 2 separate assemblies (LH (left-hand) and RH (right-hand)) incorporating a catalytic converter for each bank of cylinders. The rear section comprises 3 separate sections; a center section and two rear sections. The center section assembly incorporates a rear silencer which is connected to a center resonator silencer. On supercharger models, the center resonator is a one piece assembly with two inlet pipes from the center silencer and two outlet pipes to the rear silencers. On naturally aspirated models, each outlet pipe from the center silencer connects into an individual center resonator.
The system is attached to the underside of the body with mounting rubbers which are located on steel hanger bars that are welded to the system. The mounting rubbers locate on corresponding hangers which are welded or bolted to the underside of the vehicle body.

4.2L V8 NATURALLY ASPIRATED - FROM 2010MY (NAS Only)
The 4.2L V8 exhaust system is fabricated from stainless steel and is supplied as 5 separate assemblies. The 4.2L V8 naturally aspirated system is similar in design to the system used on the 3.0L V6 gasoline engine variant.
The front section comprises 2 separate assemblies (LH (left-hand) and RH (right-hand)) incorporating a catalytic converter for each bank of cylinders. The rear section also comprises 3 separate sections. Each section incorporates a center resonator silencer and a rear silencer.
The system is attached to the underside of the body with mounting rubbers which are located on steel hanger bars that are welded to the system. The mounting rubbers locate on corresponding hangers which are welded or bolted to the underside of the vehicle body.
