OEM Toyota Exhaust

Can you imagine what it would be like for the engine in your Toyota or Scion to be unable to clean up the noxious byproducts it creates when it burns fuel? The fumes would sicken you and your passengers, not to mention pollute the environment. Worse yet, you'd probably run afoul of emissions standards, maybe even a few laws.

Luckily, your vehicle has an exhaust to take care of the job, releasing mostly harmless water vapor and carbon dioxide afterward. There's a lot to learn about it, too. If you're looking to get to know it better, you've come to the right place: our auto parts store has the details.

Toyota & Scion Exhaust Systems FAQ

How Do They Work?

It's simple, really. Toxins pass through a catalytic converter first, where metals like platinum, rhodium, and palladium trap them and split their molecules into oxygen and nitrogen. The latter stays behind, while the former flows onward. Hydrocarbons and carbon monoxide burn up, and a resonator and muffler collaborate to optimize airflow. An exhaust manifold then sends the gases down an exhaust pipe; the muffler's tail pipe releases them, and they dissipate.

What are the Signs of a Bad One?

You can usually spot them before total exhaust failure. They include:

• Dashboard warning lights, like Check Engine
• Worsening gas mileage
• The smell of rotten eggs
• Unusual noises in the muffler and exhaust pipe

How Do You Tell When to Change Them?

That depends on which part's the problem. The easiest and best way to figure out the answer? Do an exhaust inspection. Swap out any parts that the results call for replacing. Otherwise, be sure to change your catalytic converter at 100,000-mile intervals and replace the muffler and/or resonator at 2-to-4-year intervals. You can order what you need right here online.
