Exhaust vibration reducing gum broken

Hi, so i have a problem with my exhaust [E46 05 touring].. From bottom of my car I could see "thing" attached out like cable or something. Later I checked it and it seems it was from exhaust, it's "gum" which reduces vibration. Now its detached because of corrosion. I took this gum out. I don't know should i repair it or not, because exhaust has more vibration but overall it's fine. Here are photos:

The "gum" is just a rubber exhaust hanger/isolator. The metal piece is the actual hanger which is obviously broken off. You're probably feeling vibration because the exhaust is sagging and making contact somewhere else on the car. You'll have to get the hanger welded back on, or you could possibly use one of hose universal deals from the parts store if you can find a place to mount it.

Might want to make your own thread.

Well exhaust is not sagging and its not making contact or rattle sounds because there are 2 more holders: 1 in the front and 1 in the rear and this one broken is in the middle. So like i said overall it's fine just exhaust is making more vibration than usually which is not good in long term run..
I think i should put the rubber back on metal which is attached to exhaust and hang with some tie zippers to somewhere i think it would be good solution because zippers won't melt as it only hold rubber which is hot resistant. What do you think about it? After all if you can't fix it with zip ties, you are not using enough zip ties...

They'll hold for a while, but I'd prefer something more permanent.

The rubber doesn't transfer much heat so it'll be fine. You can actually get stainless steel zip ties for a "more permanent" solution lol
