Front Section - V6 3.0L S/C Petrol AWD And RWD
The stainless steel front section is similar to both the All Wheel Drive (AWD) and Rear Wheel Drive (RWD) vehicles. The differences are; the shape of the pipes from the catalytic converters to the front silencer differ in shape slightly, the location of the post catalyst heated oxygen sensor (HO2S)'s are different and the mass damper is located on the opposite side of the left front pipe.
The front section comprises two separate pipes each incorporating a catalytic converter. Each catalytic converter has a welded pipe with a flange, which is flared into a cone which mates with the exhaust manifold. Each flange has two holes which locate on studs in the exhaust manifold and are secured with nuts. Each catalytic converter is fitted with a mid-catalyst HO2S .
A curved pipe from each catalytic converter locates into the front silencer inlet pipes of the center section. The left pipe is fitted with a mass damper which absorbs resonance from the system. Each pipe has a boss for location of the post catalyst HO2S .
