I have a 2007 Honda Accord V6. All stock. 80K miles and runs great.

About a year and a half ago, I had a noise from the rear when I would go over bumps. Took it in and it was traced to one of the rear exhaust hangers. Fixed the problem.

The noise is back. Here is a recording of it. It's easily heard from :11 mark to the :22 mark or so: https://goo.gl/photos/SePv75bGJqhoMvNg9

A friend has offered to put new ones on for me. I just need to buy the parts.

Questions:

1) This car has 4 rear hangers, correct? Does anyone know the part number, or a good place to buy them?
2) More importantly, how many more hangers (other than the 4 rear ones) does this car have? Are they exactly the same as the rubber ones in the rear? If not, what kind are they?

Thanks.
