@DG Rider @osobad - thanks for yall's post on this -I have this exact rattle and it's driving me bats***. After reading through the threads this seems like the way to go. I just want to confirm:
1- I shift the current "sleeve" , the one with 2x 12mm bolts, back toward the rear
2- then put this new clamp where the pipes overlap
3- tighten the crap out of it
4- get my sanity back from no listening to a high squeal on every ride
1. I slid the factory clamp back mainly so it would be easy to slide back up if the aftermarket clamp didn't work. I don't think it really does much, but can't hurt. There is a locating tang that will need to be flattened.
2. There is a steel ring on the front pipe. I put the aftermarket clamp directly over it so I could tighten it down more without worry about crushing the pipe.
3. Tighten it, but don't go apes***. See #2 above. Don't want to deform the pipe. Can always go tighter if it still squeaks, but loosening the clamp won't fix a deformed pipe.
4. As I said before...whoever designed this mess should be slapped to death. Or trapped in a room listening to it.
