Description
The exhaust system consists of four twin-branch manifold assemblies which direct exhaust gases through two under-floor
catalysts (before feeding) via under-floor pipework to a two-stage rear silencer.
The two-stage rear silencer directionally varies the flow of exhaust gas to give acceptable exhaust noise levels at low engine
speeds and reduce exhaust back pressure for engine protection at high engine speeds.
The exhaust valves are linked and operated via the engines ECU by means of a vacuum distribution system consisting of
an electrically operated pump, solenoid, vacuum storage tank and connecting pipework.
An illustration of the vacuum distribution system can be seen above.
