Why does my muffler make a clunking noise?
Thumping or clunking may indicate that something is broken in the exhaust system. Some mufflers contain baffles to reduce the noise of the exhaust system. These may become broken or loose and cause rattling in a muffler. Use a car jack to raise the car so you can examine the muffler. Inspect the muffler for any holes and rust.
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.
What are the dangers of a defective muffler?
A defective muffler can cause significant noise pollution and pose a hazard for any of the vehicle’s occupants. Know the risks of a defective muffler. If the muffler has a hole, it can cause dangerous gases such as carbon monoxide to leak into the cabin of a vehicle. This colorless, odorless gas is a product of the combustion process.
What are the symptoms of a broken muffler?
Excessive use or custom fabrication that is not recommended by the manufacturer. Regardless of the precise cause, broken mufflers typically exhibit a few common symptoms that will alert the vehicle’s owner that a problem exists and needs to be repaired or replaced by an ASE certified technician.

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.
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.
What are the common problems with small engines?
Rough idle, reduced power, poor fuel consumption, excessive vibration, possible change in emissions (heavy exhaust), loss of power, continual backfiring (pop), continual misfiring (sputter). SOLUTION For most of us, we’ve just stepped into “technician” territory. Diagnosing the problem is just the first step.
