Nuts!
I would have got in on these but I had to buy new stock ones a couple of months back (mine were broken, leaving the exhaust hanging). I would have preferred to spend my money on these which are much higher quality/design.
I have to agree, if both mounting points used these higher quality and dampening hangers it would probably tame drone even more. If those are ever offered, I'm going to have to suck it up and just buy a complete set.
