Freelander K Series KV6 Manifold and Exhaust System
MANIFOLD AND EXHAUST SYSTEM - K SERIES KV6
30-3-6
DESCRIPTION AND OPERATION
RH Manifold
The three branch manifold is fitted to the RH cylinder head. A composite gasket seals the manifold to the cylinder
head and four studs and nuts secure the manifold in position.
LH Manifold and Catalytic Converter
The front manifold and catalytic converter consists of a three branch manifold and a catalytic converter integrated into
a common assembly. A composite gasket seals the manifold to the LH cylinder head and four studs and nuts secure
the manifold in position. Threaded bosses are welded into the pipe at each end of the catalytic converter to
accommodate the HO2S.
RH Downpipe and Catalytic Converter
The RH downpipe and catalytic converter is connected between the RH manifold and the intermediate pipe. The
flanged connection with the RH manifold is sealed with a metal gasket. The slip joint connection with the intermediate
pipe is secured with a clamp. Threaded bosses are welded into the downpipe at each end of the catalytic converter
to accommodate the HO2S. A flexible joint is incorporated into the downpipe, near the connection with the
intermediate pipe, to absorb engine vibration. Brackets welded to the top of the downpipe accommodate anchor nuts
for the attachment of a heatshield.
LH Downpipe
The LH downpipe connects the LH manifold and catalytic converter to the intermediate pipe. Flanged connections at
each end of the downpipe are sealed with metal gaskets. A flexible joint is incorporated into the downpipe, near the
connection with the intermediate pipe, to absorb engine vibration. A bracing clamp attaches the LH downpipe to the
RH downpipe and catalytic converter. A bracket on the LH downpipe attaches the system to the Intermediate
Reduction Drive (IRD). Additional brackets welded to the top of the downpipe accommodate anchor nuts for the
attachment of a heatshield.
Intermediate Pipe
The intermediate pipe connects the downpipes to the tail silencer. A silencer is incorporated into the front of the
intermediate pipe, and the rear end of the pipe is formed to pass over the rear suspension.
Tail Silencer
The tail silencer comprises a silencer, a connecting pipe and two tail pipes. The curved connecting pipe is welded to
the left hand end of the silencer and mates with the intermediate pipe. The slip joint between the tail silencer and the
intermediate pipe is secured with a clamp.
