Your car's exhaust system has come a long way from the old days of exhaust pipes and mufflers. Today, the exhaust system is safety and emissions control rolled into one. Have your car's exhaust system inspected regularly and check it immediately if you suspect any problems. WHAT DOES IT DO The exhaust system routes dangerous exhaust gas from the engine out and away from the car to keep from affecting the occupants. Next, the exhaust system reduces exhaust noise from the engine. The catalytic converter reduces the level of harmful pollutants in the exhaust. Finally, the oxygen sensors mounted in the exhaust system monitor the level of exhaust gases to maintainefficient engine operation and to monitor the converter's operation. TYPICAL WEAR AND TEAR
