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.
