Will I need new clamps or hangers to install this?

The system uses factory mounting points, but you may need replacement rubber hangers and clamps depending on the condition of your existing hardware. Have a set on hand before you start—they're inexpensive and wear over time anyway.

Can I install this myself with basic hand tools?

Yes. You'll need a jack, jack stands, a wrench set, and maybe a rubber mallet to separate the old system from the catalytic converter. The whole job typically takes 1–2 hours in a driveway.

Does stainless steel really resist rust, or will it discolor?

Stainless won't rust through, but the tip and lower sections may develop surface discoloration (light oxidation) from road salt and heat cycles—that's normal and doesn't affect function. A quick polish keeps it shiny if that matters to you.
