Modern engines are finely tuned machines where all components must work in harmony for them to work effectively and efficiently.
Knocking or banging sound under the vehicle
If you hear banging or knocking sounds under the vehicle, especially when driving, check the exhaust mounts. It could be you have loose exhaust mounts or broken exhaust pipes.
A burning smell emitting from under the hood
The exhaust manifold is attached to the cylinder head. Between these components is the manifold gasket, also known as an exhaust gasket. If there’s a tear or leak from this component near any plastic or wiring harness, the expelling heat from the exhaust will cause these components to burn.
Poor acceleration
If you have to push down the accelerator pedal further than usual before the vehicle responds, especially from a standing point, check the exhaust system. This shows the exhaust system is not working as it should.
Bad gas mileage
A less noticeable sign of a failing exhaust system is high fuel consumption. You’ll agree that several factors can cause bad gas mileage, and one of these factors is an underperforming exhaust system.

Parts of an Exhaust System
The exhaust system of a vehicle is carefully designed to carry the toxic combustion gases away from the car. Mufflers reduce noise, while catalytic converters transform some of the toxic gases into less toxic gases.
How Does a Muffler Work?
Mufflers need a way to reduce the amplitude, or height, of the sound waves coming in, since that dictates the loudness perceived by our ears. There are a couple of ways to do so: insulation (usually fiberglass) to absorb the sound energy and turn it into heat energy, and using destructive interference to cancel out some of the sound waves.
