The exhaust system is a complex part of your car. To put it in simple terms, the exhaust system is made up of a series of components that work together to remove engine byproducts out of your vehicle in a safe manner. Below are some of the most popular exhaust system problems:

Damaged Oxygen (O2) Sensor

Most cars nowadays have multiple oxygen sensors, and they are designed to manage the fuel-air ratio. If any of your vehicle’s oxygen sensors are impaired, the computerized system in your car will not be able to attain an efficient and balanced mixture. This could result in excess gas burning and even lead to a clogged catalytic converter.


Rust can wreak havoc on your exhaust system. Driving for a little at a time too often can cause rust buildup as water vapor collects in the exhaust system. The condensation won’t get burned up as you’re not driving long enough.


Sometimes, while driving, you may have to drive over holes or bumps that can end up hurting the exhaust parts (tailpipe, etc.). As a result, you may run the risk of leaking toxic fumes into the passenger cabin.

Broken Hangers

Hangers protect the exhaust system from getting damaged when you hit bumps. If a hanger gets busted, your exhaust may be exposed and shift around, causing dents or cracks.


The exhaust system is just as important as the transmission, brakes, etc., which is why you should take it to Motorhaus as soon as you notice specific symptoms. These include:
