muffler question

Hi,

I was recently given a 1999, 6 cylinder, Camry that needs a new muffler. After taking a look at it I could see it's it's bolted on. Are they bolts, or studs welded on to the muffler, or what are they? Whatever they are, they need to be replaced. If they are a separate part, what should I buy?

Can you post a pic?

I don't have a digital camera, but I found this video on youtube: https://www.youtube.com/watch?v=7M6uH1hnNgQ

Everything is the same. Here's a screen capture.

Thanks for your help.

They are welded-on studs.
