Your Toyota vehicle's factory exhaust system is designed to safely remove all of the harmful byproducts produced when your engine burns fuel. That's important, since it helps keep you, your passengers, and the environment safe. As a bonus, your exhaust also helps muffle the noise generated in the process.

How Your Exhaust System Works

The first step involves pollutants passing through the catalytic converter. Toxic molecules are captured as they travel through, with the molecules then separated into oxygen and nitrogen. Nitrogen is trapped as the oxygen is allowed to pass, with carbon monoxide and hydrocarbons getting burned up as part of the process. The end result? Essentially water vapor and carbon dioxide.

Your exhaust manifold collects the gases and routes them to the exhaust pipe. At the same time, the resonator and muffler are reducing engine noise and ensuring maximum air flow performance. The tail pipe then releases the cleaned vapors into the air. Eventually, though, your vehicle's exhaust is going to start to fail.

How to Spot a Bad Exhaust

Fortunately, the signs of that failure are easy to spot. They include:

Reduced fuel economy
Odd noises from the exhaust pipe or muffler
You notice the smell of rotten eggs
Your "Check Engine" dash light comes on

If you experience any of these symptoms, perform an inspection of your exhaust system. If that inspection indicates that a part needs replacing, make sure that you choose the best part for your vehicle.
