Vibration/Rattle from underneath
I have a 2011 SS Vert and lately when going over bumps I have noticed a rattle/shake from underneath that at times you can feel through the floor pans. It only does it when going over larger bumps in the road but it has gotten more noticeable lately. I thought it may be a broken exhaust hanger but I got under the car yesterday and everything seemed to be tight. Just curious if anyone ever had a similar issue or may know what else to check.

With a rubber hammer hit your cats, they can be coming loose from inside. Also hit your mufflers and resonators.

When I hit them with the rubber mallet what should I be listening for? Also the car has a flowmaster exhaust so I am not sure the mufflers are causing the rattle as it is under the floorboards but I will check them. When you say coming loose from the inside what do you mean? Coming apart(failing) or just coming loose from the pipes. Thanks

The exhaust also has heat shields. Check to make sure they are not hitting anything.
When you hit the cats and mufflers they should sound solid when you hit them. If they don't they need to be replaced. |

Could be the exhaust pipe hitting the tunnel brace. It happens on my Camaro!!

Exhaust rattling against the heat shield or tunnel brace, loose connections.

I am assuming the heat shield is above the cats or x pipe. If it is hitting or rubbing is there a fix for it?
