EXHAUST SYSTEM
DESCRIPTION
The exhaust system (Fig. 1) or (Fig. 2) consists of
two front close coupled catalytic converters. Both con-
verters attach directly to the exhaust manifold using
a V-Band clamp. The exhaust down pipes exit the
converters and connect into the front resonator. The
front resonator, intermediate pipe, and muffler are
one single module. The rear resonator and tailpipe
connect to the muffler outlet. The 300M Special has

both a left and right rear resonator. The upstream
oxygen sensors are located in each exhaust manifold.
The downstream oxygen sensors are located at the
rear of each catalytic converter.
OPERATION
The exhaust system channels the exhaust gases
created by engine to the rear of the vehicle. The muf-
fler and resonator quiets the exhaust noises. The cat-
alytic converter reduces exhaust emissions.
