Exhaust Overview
Exhaust System (09.00)9-1-2 Workshop Manual Issue 5, January 2010
Exhaust System (09.00)
Exhaust Overview
The exhaust system consists of two four -branch manifolds, two catalytic converte rs, four oxygen sensors and a single
variable flow silencer assembly.
Exhaust gasses flow from the exhaust manifolds, through the catalysts and on to the rear silencer assembly.
• Two engine management oxygen sensors are mounted before the catalysts. • Two catalyst monitor oxygen sensors are mounted in
the catalysts between the primary and secondary
catalyst brick.
