I use it on Flues in my trade. Works well there. Tried it on a bung in my truck and negative on that Fyi.
Sounds like you know what and how your doing/fixing your issue, dont need our help. So when your done post a pic. better yet and before and after video would be great 👍
Dont forget to post back when done. Many dont and leave us hanging.
I understand what you are saying and I agree in most circumstances. However, Im not using it around the bung. Im going to fill the void between the inner and outer layer of the double walled pipe, using the bung hole as access only.
Its not that i dont appreciate your help, or what you are saying, because I certainly do and you are correct about silicone and exhaust bungs. But we are fixating on a detail that is irrelevant. If the inner void of a double walled pipe is full of a ring of cured silucone, the silicone "donut" cant just fall off, its stuck indefinatly between two layers of steel. It just need to sit there and absorb the vibrations isolating the outside pipe from the resonance of the inside pipe
So with the proposed fix aside, has anyine else had this issue and what did they do to stop it? Keeping in mind, this is not the same exhaust latout as a 500.
