The exhaust system collects the gases produced in the engine and routes them out of the vehicle. This, in turn, makes for a quieter ride, enhances engine performance, and helps save fuel. To determine whether your car needs exhaust repair, here are common problems affecting the system to keep on your radar. 

What Are Common Exhaust System Concerns?

1. Engine Noises

A muffler directs exhaust gases away from the vehicle and dampens the sound of the gases as they leave the system. This way, you won't hear the exhaust process from inside the cabin. If you hear noises coming from the engine, a broken muffler might be the cause. The engine noise could also be caused by exhaust leaks in the manifold or joints.  

2. Decreased Fuel Economy

Located in the exhaust manifold, oxygen sensors monitor how much oxygen mixes with fuel to complete the combustion process. If a sensor malfunctions, the engine computer won't be able to create the correct air-fuel mixture. Fuel efficiency will suffer as a result. The high fuel and low air ratio could also lead to engine overheating. 

3. Bad Smell

You shouldn't smell exhaust inside the car when you're driving. Breathing in the fumes can be dangerous, as the gas contains carbon monoxide and other harmful substances. A bad oxygen sensor could be the cause of the stench. A malfunctioning sensor can't measure exhaust gas as it leaves the combustion chamber. This can cause too much fuel to enter the engine. The excess fuel won't burn completely, which can cause a bad smell.
