1. Exhaust fumes: The muffler helps to direct exhaust fumes away from the engine and out of the vehicle. If the muffler is damaged or missing, exhaust fumes can leak into the passenger compartment, which can be dangerous to your health.
2. Noise: A damaged or missing muffler can also cause your car to be much louder than normal. This can be annoying to you and other drivers, and it can also be a violation of local noise ordinances.
3. Engine damage: In some cases, a damaged or missing muffler can cause damage to the engine. This is because the muffler helps to create back pressure in the exhaust system, which helps to keep the engine running smoothly. If the back pressure is too low, it can cause the engine to run too lean, which can damage the pistons and other engine components.
If you start your car and something blows off the muffler, it's important to have the problem repaired as soon as possible. This will help to protect your health, your vehicle, and other drivers.
