Welcome.

Inlet would be 2.25" (I.D.).

Outlet should be the same but if you notice it looks smaller, then outlet will be 2.0" (I.D.).

Just go to the auto part store, they can look it up in their system.

Walker is a fairly common muffler here.

Stainless vs non-stainless?? Your choice.

Here are some details including diameters:

It's most likely a welding job vs clamping.

Here's a selection of mufflers for a 3.3L: .
