ok if u saw my one post from a while back with all my problems

hood vibration (fixed with those rubber gromet things)
brakes ( fixed worn down pads in rear with new pads n rotors )
bumper vibration (not fixed)

bumper vibration (not fixed) <------ i came to the conclusion today when fixing my brakes that the one hanger for my exhaust is rubbing the metal n bushing on my rear sway bar causing a loud vibration noise.....

i was thinking of getting some dyamat shit that people use for sytems rattle n putting it on the hanger of my exhaust...

idk if this will work, or if nayone welse has any tips on this, but i need some dyamat to test this idea out...
