Squeaky Exhaust

I tried looking this up rather than post a question that has already been asked but could not find a post. I can’t be the only one with an annoying squeaky exhaust. First I thought it might be the suspension but it is definitely the exhaust. I had a custom Magnaflow made and installed about a year ago and now I have this annoying squeak. I got under the truck to isolate and it is either the rubber hangers or the spring tension bolts. I lubed all the pivot points tightened the tension springs and even high-temp lubed them but it still persist but not as bad. I know it is the exhaust because it happens only when I grab the exhaust tip and move it back and forth. Any suggestions or experiences with this problem?

 

If you shake the tip more than twice that considered playing

 

A custom magna-flow? Put the stock exhaust back on
