Is this an OEM muffler for 2007 Sedan?

Hey guys I saw this on eBay and it looks a lot like the stock one. So is this a stock one?

Yes and the walker replacement is junk. Why are you replacing the muffler anyways?

The pipe leading to the bulb looking silencer is rusted. So it’s much easier to replace the whole thing.

Is it easy to take off the bolts from the flange? I was thinking about re-using the flange bolts from factory if I can or if the ebay one doesn’t come with the flange bolts.

I noticed this one from amazon says comes with flange bolts:
