When the engine in your SUV, pickup, car, or van burns fuel, it produces harmful byproducts as a result. Your vehicle's exhaust system has the responsibility of removing those noxious elements so that cleaner gases are emitted into the atmosphere. That keeps the air cleaner, benefitting you, your passengers, and our shared environment.

How Your Exhaust System Works

Exhaust systems work in three stages. First off, pollutants pass through a catalytic converter. There, metals capture the toxic molecules and separate them into oxygen and nitrogen. Nitrogen gets retained, while the oxygen continues through the system. The process burns any hydrocarbons and carbon monoxide, leaving little more than carbon dioxide and water vapor.

Then the exhaust manifold collects the gases and sends them to the exhaust pipe. While that's happening, your resonator and muffler optimize the airflow and limit engine noise. Finally, the tail pipe releases the cleaner fumes into the air.

How to Spot Exhaust System Problems

Automotive exhaust systems don't last forever, though. Even the best can eventually fail. Signs of trouble include:

Poorer fuel economy

Weird noises coming from your muffler and exhaust pipe

You notice the smell of rotten eggs

A lit "Check Engine" dash warning light
