Car Care - About Mufflers & Exhaust

Your exhaust emission system really starts at the front of your car, right behind your engine. Exhaust manifolds connect to the cylinder heads, where they collect exhaust gases. As the gases move through the exhaust system, they are first analyzed by oxygen sensors, refined by the catalytic converter, and finally, muffled by the muffler. So by the time those gases leave the vehicle, your emission system has made your car run smoothly, cleanly, and quietly.

It is a complex system, but our expert factory trained technicians can diagnose the problem and get you right back on the road.



Your exhaust emission system does all of its important work while hanging precariously from the bottom of your vehicle. So to help keep your car running smoothly, quietly, and efficiently, we recommend having your exhaust system checked at least once a year.

Common Signs of Wear

• Exhaust manifolds and gaskets: cracks or small holes could cause exhaust leaks, affecting both safety and performance
• Oxygen sensors: cracks, damaged wires, or blocked intakes could cause incorrect fuel/air mixture adjustments and poor fuel economy
• Catalytic converters: overheating, dents, clogs, or corrosion could cause air pollution, excessive noise and rough idle
• Resonators and mufflers: excessive rust or holes could cause air pollution, excessive noise and a rough idle
• Pipes, hangers, clamps, and brackets: excessive rust or broken bolts could cause parts to hang dangerously low, resulting in a hazard for the people driving behind you
