I have had for some time some exhaust noise/vibrations, and decided to buy a new exhaust. However when I checked the exhaust I couldn't find any holes or any bad rubber holders. I decided to not change it and investigate some more.

The noise increased and it seems like the exhaust has been lying on some metal making the noise marked with red. Metal Issue

I can turn the rubber holders of the exhaust to remove the sound, but how can it be that this is hitting the metal: The image shows the one that has been turned.

Turned rubber

But this holder and also the other rubber holders look to be fine - to the best of my knowledge. Is there supposed to be rubber on the metal the exhaust is hitting? Or how can this happen?

After turning

It seems now the noise has disappeared, and it has not been turning back. I find this really weird how that can happen. Is there some issue with the rubber exhaust hanger? Is it general that they make this noise polos from 2013?

  • Looking at the top image ... there appears to be plenty of clearance there. Also, I'm not seeing any indication of fresh metal (metal-to-metal contact would show a fresh, rust free area rubbed into it). I'm wondering how did you came to the conclusion this is where the metal-to-metal contact is happening? Nov 5 '20 at 11:57
  • In the top image, the exhaust looks as though it is not central in the arch it passes through. Perhaps the seam/lip around the end of the can is knocking against the arch, on the left. Nov 5 '20 at 12:49
  • @Pᴀᴜʟsᴛᴇʀ2 I had it lifted up, and the banging noise disappeard as soon as I lifted the exhaust up a bit.

  • @WeatherVane I could not see it, but maybe I am misunderstanding what you mean.
