Termignoni wobble

Good morning gents.

I took my Termis off the Monster last weekend to scotch-brite the Ba-Jesus out of the mid pipe, as it was looking a bit worse for wear. The silencers slid off nicely, but I noticed when reassembling it that they were a little bit loose.

The hanger that drops down from the pillion seat wasn't the issue, it seems that the cleaning the adjoining exhaust parts has taken away some of the resistance between them.

I've had a look online for some solutions and it seems someone across the pond has had a similar issue with their bike.

Any suggestions like a high-temp exhaust paste that might help stop them from wobbling?
I don't think it's creating a leak, it's more of a piece of mind thing.

Thanks!
Tom
