Wrap the entire exhaust pipe of the car with fiberglass cloth. Can you reduce noise? Does it affect the exhaust pipe and the service life of the car? Thank you
I would suggest that you find a muffler that is different from your model, a little larger and a little better. It's more convenient to change it directly. You can turn to the market and look for it.
It looks like it's fiberglass stone. It works, but it doesn't help. There's nothing wrong with life, but it can cause the exhaust fan to heat up and cause trouble.
Exhaust noise mainly in the rear, the middle is not very sound, and even if the effect is not obvious. Because the noise in the driving process is mostly due to vibration of the body resonance. It is recommended to do all the car sound insulation. Feel you want to do it yourself, buy car noise proof material, and glue it to the hood and inside the trunk with 3m. In a word, large pieces of flat iron can cause more serious shocks. And the sound insulation materials are absorbed by these vibrations, so as to play a role in sound insulation.. Hope to adopt.. Between your questions, 1 can reduce, but the effect is very small, because the exhaust is not the main source of noise, 2, may accelerate corrosion, because it will lead to rainy days, the exhaust pipe water can not evaporate in time.
