The factory exhaust in your Toyota Matrix has many parts. Together, they work in stages to clean and get rid of the fumes your hatchback's engine creates as it burns fuel. Your catalytic converter is first. It captures the pollutants produced during combustion. Using a safe, contained chemical reaction, it converts them into a gas consisting of water vapor and carbon dioxide. Your exhaust manifold then collects the gas. It sends it down your exhaust pipe. Meanwhile, your resonator and muffler help make sure the gas flows as freely as it can. Lastly, your tail pipe expels cleaner fumes, dispersing them into the air. This process protects you, your passengers, and the environment alike. When should you replace exhaust parts? How often should you change them? That depends on what part, how you drive, and the conditions you normally drive in. A catalytic converter might last as many as 100,000 miles, but a muffler or resonator may only be good for 2 to 4 years. A better way to answer these questions is to look for symptoms of exhaust problems beyond your Check Engine light. They include everything from strange noises coming from your exhaust pipe and muffler to lower fuel economy and that telltale smell of rotten eggs. If your car shows these signs, do an inspection. If your exhaust is the cause, it'll tell you. If you need to order new exhaust parts for your Toyota Matrix, buy genuine. Your OEM guarantees their compatibility with your model. You're in luck, too.
