101 on Your Vehicle's Exhaust System

One of your vehicle's most important components is its exhaust system. It manages and expels waste carbon dioxide (CO2), carbon monoxide (CO), and other harmful substances generated by your engine's combustion process.

A working exhaust system provides benefits such as emissions control, improved engine performance, noise reduction, and better fuel economy. Your exhaust system's catalytic converters work hard to initiate chemical reactions that convert toxic gases into neutral substances, allowing you to meet environmental regulations with vehicle use.

Apart from emissions control, vehicle exhaust systems help maintain optimal engine performance. The more efficiently exhaust gases are expelled from your engine, the better your engine will perform. Likewise, noise reduction is improved when mufflers and silencers properly quiet the exhaust process using sound-dampening materials and noise-attenuating chambers.
