When I press on the tips, it makes a squeak noise and sometimes it changes to like a vibration or tapping sound... I have tried to use some WD40 to spray on all 4 hangers but still having this issue. the shop that installed my headers mentioned it might be from the suitcase insulator? Does anybody know what I can do 
I attached a video below... It looks like the tips are rubbing against the diffuser but after making some clearance, its still like that...
NEED SOME HELP

Worked on that same exhaust setup on my 1le 2 weekends ago. In fact had to replace the passenger side due to valve rattle. Someone also pointed out about the bracket. That bracket has 3 holes, 2 is used to bolt it on the car and the other has the gasket acts as a hanger. Make sure those 2 bolts are tight. You definitely need to loosen up all of your clamp bolts and reorganize the tips. The tips should not be touching anywhere with good clearance. You can definitely melt that diffuser and hear noises. Finally, make sure the muffler itself is not hitting the heatshield above. Again it requires you to loosen up all clamps and rearranging the mufflers. Don’t assume the exhaust tips have to slide all the way in to the muffler, some do and some stick out an inch or two. At the end of the day, make sure nothing is touching, the center of the tips are aligned and driver side is matching passenger side as far as how much the tips are sticking out. Good luck!
