I found this today in my driveway...pretty sure it's off my RX300...anyone have any ideas where this part belongs or what it is?

 

Welcome to Club Lexus!

I vaguely remember another thread that had a picture of something similar to this, and I don't remember exactly what it was for (something to do with balancing the weight) but one thing I do remember is that it was useless. < *this may have nothing to do with what's pictured here*

Hopefully someone has more helpful information.

You're welcome!

 

That's the thread! LOL, I clearly remembered wrong though.

 

Thanks so much! Makes me feel better knowing I can drive safely without it

 

Safely, yes, but it is not a useless part.

It is a harmonic damper in the exhaust system to subside harmonics.

So removed from my RX a long time ago along with other extra weight.
