identify this part 2013 Prius II

Yes that's an exhaust hanger rubber and rod and expanded round The expanded round pushes through the rubber and then the rubber hangs on a slot sticking out from the chassis It's all exhaust related so that the exhaust doesn't rattle when the car is running turning and driving That's not necessarily going to hurt anything but when you're around a Midas or an exhaust shop just pull in and let them lift the car up that'll take 5 seconds for the guy to bend and put the rubber back on he'll actually feel bad about possibly charging you for it but anytime he has to do anything you have to pay something this is a quick fix with a large pair of channel locks to grab and bend and possibly a few strikes with a small hammer without breaking or tearing up anything this is generally a pretty easy repair If the rubber piece is damaged they'll have new ones at the exhaust shop they're about six bucks a piece You kind of want to get the exhaust suspended on the rubbers again It keeps everything nice looks like she may have caught something in the parking lot or possibly on not so well paved road or what have you The Prius is pretty low to the ground this is a good time also for the exhaust shop to generally look at the exhaust and see if there's a few spots that normally need it to be jacked up on the exhaust usually the pipe going from the cat back to the muffler is a hanger as in it hangs down too low I make my exhaust guy pick up that piece with his stand and bend it so it stays up so when I look under the car I don't see that piece It's hugged up under the car in the tunnel most Prius when I ride behind them this piece is hanging down ready to hit a rock or a parking curb if you're inclined to drive over those so we don't have that and if you take a picture leaning down from behind my car You won't see the exhaust pipe on every other Prius I see in the country I can see it when I'm driving behind it It's like a Z bend like a CIBE Z beam pattern looking shape

 

It's to hold the exhaust up. You'll have to bent it back up so the top of the
rubber part aligns with metal part on the right side of the photo.
The metal part on the left that has the rubber hanger on it will be below the part on the right
but they will be parallel.

 

??? What welding??? Just raise that side of the car, then take a large cresent
wrench and bend it back up.
Or a hammer and bang it back up....
That's pretty sad of those people.... can't fix a simple thing lik that???

 

When you get there they'll probably bend that piece up Make sure that it's strong enough to stay up If not they'll tack it or something and then hang that piece of rubber back over that round ball of an end on the piece that's bent and then look at it bend it until it looks reasonably straight and then you're off and running try to be more careful of what might be getting caught under the car maybe you live on the dirt road or a rock driveway or something A stick sitting sideways with a limb sticking out of it a little bit that looks like you could clear could do this.

 

For the exhaust hanger bar to get that bent there might be other damage; any responsible shop doing the exhaust repair should check on that as well. One scenario would be an object on the road kicked up, levered the hanger bar. But yeah have it all looked over.
