Why is my exhaust suddenly loud?
A muffler that is suddenly noisy is often caused by the driver hitting something while on the road, damaging the exhaust system. Rust can also be a culprit of holes in the muffler, resulting in a noisy muffler which gets progressively worse as the holes get bigger.
Why is my exhaust blowing?
In time, this heat causes first cracks, and eventually, small holes, to form. These are what cause the phenomenon known as ‘blowing’, which creates the distinctive resonating noise and vibration which is a symptom of the exhaust being about to fail.
How do you know if you have a bad EGT sensor?
One of the first symptoms commonly associated with a bad or failing EGR temperature sensor is engine ping or knock. If the EGR temperature sensor malfunctions it will cause issue with the EGR system flow. This can cause cylinder temperatures to rise, which can cause engine ping or knock.

Why does my car sound extremely loud?
One of the most common causes of a loud vehicle is an exhaust leak. The exhaust system carries very hot hazardous fumes out of the engine, away from the passenger cabin and releases them as less harmful emissions at the rear of the vehicle.
Why did my car get louder all of a sudden?
An engine that is suddenly running louder than normal is usually crying for help. In the majority of cases an underlying problem is causing the engine to rumble. Problems can range from something simple like dirty spark plugs to the more serious failing muffler or catalytic converter.

Items close to your car’s exhaust pipe, such as exhaust connectors, exhaust rubber hanger, or loose exhaust bracket, could come into contact with the muffler by accident, causing that rattling noise in the muffler, especially when you accelerate.
Where is the EGT sensor located?
The exhaust gas temperature sensor (EGTS), which is located in front of Diesel Oxidation Catalyst (DOC) and/or in front of Diesel Particulate Filter (DPF), detects exhaust gas temperature and converts it into a voltage and feedback engine ECU with the voltage signal in order to control engine condition to effectively …
Why is my car shaking when stationary?
If the vehicle shakes or the engine shudders a lot when stopped at a stoplight, or when parked with the engine idling, it might indicate the motor mounts or transmission mounts are damaged or broken. If the shaking decreases, it’s a strong indicator the engine’s motor mounts need to be inspected by a mechanic.
Can a bad muffler cause car to shake?
An exhaust leak can cause your vehicle to shake and vibrate as the hazardous fumes escape from what is likely, a pretty small hole in the exhaust system. In many cases the gas pedal will generate the vibration, but it can be felt elsewhere, particularly during acceleration.
