MANIFOLDS AND EXHAUST SYSTEM
Description
The exhaust systems fitted on all models with the
300Tdi engine comprise three sections; front pipe
assembly, intermediate silencer assembly, and tail
pipe and silencer assembly. All sections, including
silencers, are manufactured from luminised steel to
give the system a durable working life under all
conditions. Special clamps are provided to ensure
leak proof jointing between the various sections,
which are supported by flexible rubber mountings.
Catalytic convertor
When fitted, the catalytic converter is integral with the
front pipe assembly, which also incorporates a flexible
joint. The catalyst forms part of the engine emission
control that can also include an EGR valve system
