A muffler plays a vital role in a car as it helps reduce exhaust noises and filter exhaust fumes from the engine. But over time, it may get worn out due to several factors.
When this happens, so many things will go wrong with the overall functionality of your car.
The best course of action will be to either repair or replace it. Muffler replacement cost/muffler repair cost may vary from brand to brand, with many other factors considered.
It cost around $30 to $400 for repair, while between $75 to $750 to replace a muffler.
Muffler and how it works
The muffler is located in the rear of many vehicles. It has tubes inside bent downwards to shove away exhaust gases and noise created by the exhaust valves.
How? As the engine works, it releases gases into the exhaust pipes.
This exhaust gas goes into the muffler, which filters the gas and sends it out through a tube. The tube generates a sound wave opposite the disturbance created by the engine.
This process absorbs the sound before the noise is finally released through the main muffler.
But if your muffler is not in place, the noise and fumes come out raw, causing noise and air pollution. So how do you know the muffler is faulty and needs fixing?
Symptoms of a Faulty Muffler
One of the easiest ways to identify a faulty muffler is to look out for the sound your car makes. A broken muffler will usually make a loud noise than usual.
The muffler consists of many chambers that help absorb the vibration created by the exhaust system.
Once it is compromised, it can result in an exhaust leak causing different noises in the exhaust pipe.
Note that in most US states, it is illegal to drive with a bad muffler because of the air and noise pollution it causes.
Make a physical inspection
You can identify a bad muffler by checking its physical state. Holes and rust on the muffler may indicate that it is faulty.
While a small amount of rust is normal, a reasonable amount of rust on the outside may indicate severe complications.
If the muffler drips and shows signs of rust, the issue might be worse. As the exhaust system cools down, condensation occurs, leaving steam in the exhaust system.
Over time, the liquids cause rust in the exhaust, which in turn causes exhaust leaks.
Most manufacturers included a small drainage hole in the muffler to remove water from the muffler.
But if the drip is extensive or comes from multiple holes, you may need to replace it. Holes may have formed due to rust.
A faulty muffler can result in blockages in the exhaust system leading to a high temperature or loss of power.
To confirm the issue is from the muffler, switch on your car and leave it idle for a few minutes. If you observe a temperature rise, you will need to check the muffler.
Reduced fuel economy
Exhaust leaks that stem from a damaged muffler affect oxygen sensors in your car.
The oxygen sensors are part of the fuel injection system that helps manage how a car consumes fuel.
When these sensors are bad, they can’t determine the amount of exhaust in the exhaust system. Thus giving false readings, which invariably decreases fuel economy.
Smell of fumes
One function of the muffler is to divert exhaust gases out of your vehicle. If it is faulty, these gases are sent back into the car.
These gases smell bad and can cause headaches, dizziness, or other health issues. When this happens, the right thing will be to take your car to a mechanic for a proper diagnosis.
If, as your drive, you start experiencing constant vibrations, it can point to a faulty muffler.
The best option will be to take the car to a mechanic and explain how the vibration sounds and where it comes from.
While the muffler might be a culprit, the vibration could also result from poor engine performance or faulty steering. Only a proper diagnosis can state the cause of the vibration.
Car Muffler Replacement Cost
The average cost of muffler replacement could be between $75 to $750, depending on different factors. This may include, what needs to be replaced, the car model, and the labor involved. A new muffler costs between $25 to $500.

If the vehicle has been driven in harsh conditions such as rain, ice, or salty roads, the muffler could be clogged.
When this happens, many other systems like the hanger, silencer, and gaskets could be damaged. And thus, need to be replaced along with the faulty muffler.
This could add an extra $20 or more to the muffler installation cost.
A completely bad resonator pipe will amount to an additional $100 to $150 to repair costs. While a faulty exhaust tip will add an extra $25 to $50.

Exhaust system replacement cost

This post popped up at the right time! Thank you, Leo!
My car had been pretty loud the last few days, and last night, I saw that the muffler had completely rusted off. It looked like there was no real risk of it falling off or dragging.
I don’t think I’ll be able to take it in to be repaired for about 6 days. Is it safe to drive until next week?
