What are the effects of a broken car muffler?

When a car muffler is broken, it will cause the engine sound to increase. Here is the relevant introduction: Introduction to car mufflers: A car muffler is a component used to reduce the noise generated by the engine during operation. Due to the length difference between two pipes being equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when superimposed, canceling each other out and reducing the sound intensity, thereby achieving a noise reduction effect. Main functions: Reduce the exhaust noise of the engine and allow high-temperature exhaust gases to be safely and effectively discharged. As part of the exhaust system, the muffler should ensure smooth exhaust flow, low resistance, and sufficient strength. The muffler must withstand high-temperature exhaust gases ranging from 500°C to 700°C, ensuring that it does not get damaged or lose its noise reduction effect within the specified mileage of the car.

I've loved cars since I was a child. If the muffler breaks, it's a big problem. First, the noise level immediately skyrockets, making driving sound like operating a tractor with constant rumbling – completely ruining the driving experience. Poor exhaust flow causes changes in engine backpressure, resulting in weaker power, sluggish acceleration, and noticeably increased fuel consumption. I tested it last time, and it consumed an extra 0.5 liters per 100 kilometers, which hurts the wallet. Leaking exhaust fumes entering the cabin also pose a carbon monoxide poisoning risk, especially in enclosed spaces like garages – this is a deadly hazard. Get it fixed ASAP; I recommend going to a professional shop to replace it with stainless steel components for durability and quietness. In short, don’t delay, or the car’s condition will worsen.

I drive my kids to school every day, and having a faulty muffler is really annoying. The car is as loud as firecrackers, with my kids covering their ears in the back seat, and neighbors knocking on the door to complain about the noise. Performance-wise, acceleration isn't as smooth as before, the power feels weak, and even driving on the highway is a struggle. Exhaust leaks could also let fumes seep into the cabin, especially when using the heater in winter, increasing the risk of carbon monoxide poisoning for my kids—I get scared every time I research it. Repairs aren't cheap, ranging from a few hundred to over a thousand, not to mention the wasted time for drop-offs and pickups. I recommend checking the exhaust system regularly—safety first.

As an experienced driver, a broken muffler is a common hassle. The noise increases, the driving experience deteriorates, and exhaust leaks may cause odors inside the cabin, posing significant health risks. Fuel consumption also rises, and engine efficiency drops. I encountered a similar issue when I was younger, and timely repairs helped avoid accidents.
