The exhaust of your car plays an important role in letting the engine of your vehicle “breathe” by simply diverting the toxic fumes and gases away from the engine via the tailpipe and catalytic converter. But these parts have a limited lifespan since these fumes and gasses deteriorate the oxygen sensors, the metal using which these parts are made, and the precious metal in your catalytic converter.
Automakers, over the years, have developed highly sophisticated ways to boost efficiency, limit emissions, and reduce noise. The exhaust system consists of the piping, muffler, and catalytic converter that helps reduce pollution. Exhaust systems are usually resilient and issues that occur in them are frequently a sign of something else wrong in the car. Still, it is vital to be watchful about the prospective exhaust issues.

Signs of muffler or exhaust system issues include:

You have noticed a drop in your car’s performance or fuel efficiency.
Your car is noisier than usual.
The exhaust pipe is dragging on the ground
There is an unusual smell coming from the exhaust.
There is a hissing sound coming from the exhaust.
Smell of fumes in your car.
Rust on your exhaust pipe.
