go to homedepot and look in the hose clamp section...LOL :-D :-D

yeah I know they wouldn't look right, you could always use bread ties, lol....:-D

 

Those are called muffler bearings.

 

they have a rubber insert, that makes them sealed muffler bearings, how did you not know that lol

 

Call Jardine. 951-739-5900. Jardineproducts.com. I used to have a pair of the round black powdercoats and was able to order individual replacement parts, in my case a new midpipe, but I'm sure they'll sell you new muffler clamps. By the way the ones in the pic are not Jardines for the round black cans-are they just for reference or are those the ones your looking to replace. They look more like two bros or leo vincis.
