Are they supposed to move real easy? i have been havving this rattleing noise in the back of the car and i can easy(very) move my muffler from side to side. And i have found that the noise comes from the rubber part hitting part of the car.
So i was just wondering. These are supposed to be very firm and in place back there right?

 

they're meant to flex a little, although they can get old.

I've seen urethane ones that don't flex as much.

maybe try replacing yours.

 

did you get your exhuast removed/installed lately, make sure everything is aligned and all the bolts are tight.

 

i did put a test pipe on. but this started like 2 weeks after.

 

may be a heat shield rattling against the test pipe, that's what was causing my rattle.

no it is the rubber part rubbing the back.
