CATALYTIC CONVERTER
DESCRIPTION
California emissions vehicles incorporate mini cat-
alytic converters into the exhaust system. The pipes
and catalytic converters are made of stainless steel
designed to operate at extremely high temperatures
(Fig. 2).
OPERATION
The catalytic converter captures and burns any
unburned fuel mixture exiting the combustion cham-
bers during the exhaust stroke of the engine. This
process aids in reducing emissions output.
EXHAUST PIPE
DESCRIPTION
The exhaust pipe(s) is a one piece design encom-
passing the exhaust pipe(s) and the catalytic convert-
er(s). Neither the exhaust pipe(s) or the catalytic
converter(s) is serviceable separately (Fig. 3).
MUFFLER
DESCRIPTION
All engines use a stainless steel muffler to control
exhaust noise levels and exhaust back pressure (Fig.
4).
