One thing I noticed when I installed the clamp was that one of the clamps that clamp down the clamp was partially in front of the lip of the main clamp. This I would think would prevent the proper tightening of the main clamp on that side. I had to unscrew the one side of the tightening clamp in order to push it over the lip of the main clamp. After that the clamp tightened down without any problems and hopefully it will stay put.
But I will keep checking it for leaks in a few days.
So far no vibration noises or clicking noises or any type of noises. Just a nice sounding exhaust. I love that tip. It looks massive but not overpowering. It fits that cutout perfectly.
