Exhaust System: Description and Operation

EXHAUST SYSTEM
DESCRIPTION
The exhaust system on the 2.0L/2.4L engine models consists of a front mounted catalytic converter, resonator/pipe assembly, muffler/pipe assembly, band clamps, and support isolators. The upstream oxygen sensor is located in the exhaust manifold. The downstream oxygen sensor is located in the catalytic converter.

The exhaust system on the 2.7L engine model consists of front and rear bank catalytic converters, cross-under pipe, connector pipe, resonator/pipe assembly, muffler/pipe assembly, band clamps, and support isolators. The upstream oxygen sensors are located in the front and rear exhaust manifolds. The downstream oxygen sensors are located in the crossunder pipe.











Resonators, mufflers, and exhaust pipes are tuned to each powertrain combination. (Fig. 1), (Fig. 2), and (Fig. 3).
