Why is my muffler so loud under deceleration?
If the muffler has a hole inside the unit and loses its efficiency, it can cause misfiring in the engine, particularly when under deceleration. 2. Exhaust is louder than normal Loud exhaust noise is usually the result of an exhaust leak that commonly occurs in the muffler as opposed to the exhaust components located near the engine.
What happens if you listen for exhaust noise?
You don’t want to end up on YouTube as the person chasing their running car down the street. Or worse than that, you could be badly hurt by a vehicle that suddenly starts to roll while you are on the ground listening for exhaust notes.
What causes the muffler on a car to go bad?
3. Condensation from the exhaust pipes. When the exhaust system, including the muffler, cools down from the engine being run, the moisture in the air condenses inside the exhaust pipe and the muffler. This moisture sits there and slowly eats away at the exhaust pipe and the shell of the muffler.
Why do waves in a muffler not register as noise?
When these waves reach the ear, they don’t register as noise simply because they cancel each other out. Inside the muffler are tubes that are specially designed to produce pressure waves that are reflected and interfere with each other; thus, canceling each other out.
What happens to an engine when there is no muffler?
This includes bends in the tubing, catalytic converters and mufflers. Exhaust restrictions increase pressure in the system, which keeps used gases trapped inside of the engine’s combustion chambers. These gases take up space that should be occupied by fresh air and fuel. The end result is a loss of engine performance and fuel economy.

Can a bad muffler cause engine misfiring?
Engine is misfiring. When any of these components are damaged, it can impact vehicle performance, including causing engine misfiring. If the muffler has a hole inside the unit and loses its efficiency, it can cause misfiring in the engine, particularly when under deceleration.
Why does the exhaust go through the muffler?
As engine exhaust flows through the exhaust system, it is contained and eventually flows through the muffler. Inside the muffler is a series of chambers that helps to reduce the vibrations coming through the exhaust which is commonly associated with sound.
