GAS ENGINES




Figure 1 Exhaust System - Typical - SWB







The exhaust system consists of a catalytic converter (1), muffler (6), and a resonator (5) with connecting pipes in-between. The system is serviced in two sections; the catalytic converter and pipe, and the muffler and resonator with connecting pipe.

A band clamp is used to connect the joint between the two components. Three support hanger rods with rubber isolators are used to support and isolate the exhaust system. A flexible joint, integral to the catalytic converter, allows for engine movement. The exhaust system is tuned for each vehicle/powertrain combination.
