Unless you love attention, most people don't want to alert everyone with a loud roaring car. It can be embarrassing for the driver, and you could be faced with many noise complaints. Most of the time, the noisy sound that cars produce stems from an irregularity in the vehicle's exhaust system.
Many exhaust systems in newer automobiles may now last well beyond 100,000 miles without any problems. But because most of the exhaust system is exposed to the conditions of the road, damage may occur without notice. These are some of the parts of the exhaust system that can be damaged and emit noise:
Puncture or Crack in Muffler
The most common cause of a high-pitched noise from your vehicle is any punctures in your muffler. A damaged muffler is more severe than you may think. In addition to noise pollution, your muffler may be expelling hazardous exhaust fumes. Your engine byproducts contain carbon monoxide, a gas that can make you humans very sick. If you suspect you have a leaky exhaust, you should take it to a trusted mechanic pronto.
Leak in Exhaust Manifold
If you hear a popping or puffing sound coming from the motor, you're probably dealing with a leak. The exhaust manifold is a part that collects the exhaust gases. If there is the slightest leak, all the exhaust will escape.
Bad Catalytic Converter
A catalytic converter is a critical component of the exhaust system that changes the harmful gases into safer air. It is positioned between your engine and exhaust muffler on the undercarriage of the vehicle. If noises or vibrations are coming from this area, it is a cause for concern. A failing catalytic converter can degrade your car's performance and give you a delay in acceleration.
Poorly Matched Resonator
If you recently had your muffler replaced and you notice a sound when you press on the gas pedal, it could simply be that the resonator isn't applied correctly. The body of the resonator is designed to silence noise and is outfitted onto your muffler. If it is replaced with a straight pipe or a poorly designed resonator, it will not be able to dampen the sound.
