On my 2009 sedan, there are plastic pucks or disks attached to the mufflers pointing towards the tires. Are these the TPMS receivers? I don't see any wires leading to them so unless they work on wireless and induction or black magic I have no idea what they can be.

Thank-you!

 

I had an 09 sedan and I don't remember anything like that. Can you post a good photo of what you're talking about?

 

When describing something like this it's always best to post a reference picture for people. It'll be easier and you'll get responses much quicker!

 

It's a vibration damper.
It is made of a specific mass connected by a " visco-elastic substance" (rubber) that reduces the vibration. There is also one on our transmission.

 

Sounds heavy, throw it away.

 

Here is what I am asking about. Muffler on the left...rear tire to the right (out of frame).

 

Thank-you for the replies!

Cheers

 

You poor Snow Belt guys having to deal with salt!

 

 

These are on the y pipe as well. They do a pretty good job actually. I have been thinking of a way to integrate these with my custom axleback
