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...

 

I wrapped heat wrap around the area where the exhaust touches the bar. It worked so so.

 

Dynamat is NOT designed to deal with exhaust heat under direct contact. You may want to have the piperelocated slightly.

 

see if you can loosen the axleback to position the exhaust so its not rubbing up against it

 

on my lower rear tie i had the same problem. what i did though is took the bolt that hangs my canister and moved it up to a bolt that was about 1 inch closer to the bumper, creating a small 1 inch gap between the bar the pipe leading to my canister. i had it on the lift when i did that though so you might have to do that or at least crawl or wheel around on a creeper.
