- If you hear rattling sounds the most common cause is loose clamps or brackets. Loose clamps and brackets can be tightened but any corroded elements must be replaced.
- If your vehicle sounds louder than normal or you hear a ticking sound when accelerating it may indicate an exhaust leak due to corrosion.
- If your check engine or service engine light comes on it may indicate a faulty or failing catalytic converter.
- The smell of rotten eggs or burning could indicate a problem with the catalytic converter.
- The smell of exhaust fumes may indicate an exhaust leak that can be potential dangerous to you as carbon monoxide may seep into the vehicle.
Note:Excessive idling allows water to condense in your exhaust system, which can lead to corrosion.
Exhaust System Components
An exhaust system reduces noise and helps prevent harmful emissions from escaping into the environment.
If you've ever heard a car running without a muffler, you know what a huge difference a muffler makes to the noise level. Inside a muffler, you'll find a deceptively simple set of tubes with holes in them. These tubes and chambers are as finely tuned as a musical instrument. They are designed to reflect the sound waves produced by the engine in such a way that they partially cancel themselves out.
Some vehicles have a resonator, which in combination with the muffler further reduces the sound that is produced by your engine. It looks similar to a muffler and contains a specific volume of air and exact length for your vehicle to help cancel out certain frequencies of sound in the exhaust.
The catalytic converter closely resembles a muffler in appearance but its primary function is to reduce the harmful emissions in a vehicles exhaust. It changes carbon monoxide, hydrocarbons and oxides of nitrogen into harmless carbon dioxides, nitrogen, oxygen and water. The catalytic converter achieves optimum performance at between 450 and 800 degrees Celsius and when fully warmed up contributes to better fuel economy and cleaner exhaust.
The oxygen sensor is positioned in the exhaust pipe and the goal of the sensor is to help the engine run efficiently and produce as few emissions as possible. It monitors the amount of oxygen found in the exhaust gases and communicates to information to the engine's computer. The computer then adjusts the mixture to ensure the cleanest combustion possible.

A conventional muffler produces backpressure because of all the holes, chambers and turns the exhaust has to go through. This backpressure robs the engine of some of its power.
A performance muffler, on the other hand, allows the exhaust to go straight through, thereby reducing the backpressure, which increases your engines performance. This type of muffler does not reduce the sound as much as conventional mufflers.
