OVERVIEW
The exhaust system is fabricated from stainless steel and is supplied as three separate assemblies;
A front section incorporating a catalytic converter
A center section incorporating a center muffler
A rear section incorporating a rear muffler.
The system is attached to the underside of the body with three mounting rubbers which are located on mild steel hanger
bars that are welded to the system. The mounting rubbers locate on corresponding hangers which are welded to the
underside of the vehicle body.
The system has service repair items available for the down pipe and crossover pipe. Indentations with arrows show the
cut points for the service replacement front section. When a service repair section is used, the pipes at the service joint
are connected using an end to end sleeve clamp at the cut points.
FRONT SECTION
The front section has a welded flange with four M10 studs which provide for the attachment to four holes on the
turbocharger. There is also a location bracket that connects the rear two studs back to the manifold; these are secured
to the Turbocharger using four M10 nuts.
The flange is welded to the catalyst inlet cone which in turn is welded to the catalyst body. An outlet cone is welded to
the bottom of the catalyst. This has an outlet elbow pipe welded to it. The outlet elbow and outlet pipe are 60mm
(2.36in) O/diameter x 1.5mm (0.06in) thick wall tube. A de-coupler is welded between the outlet elbow and outlet pipe.
The catalyst is attached to the engine via a mounting bracket which is bolted to the engine using two M8 bolts.
