Does driving with a noisy muffler damage the car?
ask any gangstalker ( members of covert harassment programs) they should know
If your car knocks, grinds, squeaks and makes other unholy noises, it may have a bad muffler. A muffler is basically a series of tubes and chambers located under the car at its back end. Mufflers quiet the noise made by the engine and reduce noxious emissions. If your car's muffler isn't working, you're polluting the atmosphere with fumes and unpleasant noise every time you go for a drive.
The Property Damage coverage on the car you were driving should cover the damage to your own car. In the event that the car you were driving didn't have insurance coverage then you may be able to make a claim under your own Collision coverage or Uninsured Motorist Property Damage coverage could apply.
You can drive a car without a muffler, but you should not. It is illegal. Driving without a muffler allows many pollutants into the air. Technically yes, a car can be driven without a muffler but there are a few good reasons not to do so. The most important risk of not having a muffler is that there are laws regarding sound levels and a car without a muffler might be over government approved noise…
If you hit an object on the freeway and caused damage to a friend's car can you be held liable for the damage or deductible in CA?
More than likely, yes. The car was the responsibility of the person driving it at the time of damage, regardless of the circumstances. You are NOT liable for any part of the damage (including deductible) as long as you are driving with your friend's permission. No, you are not responsible for the damage.
