Will this bolt directly to my stock catalytic converter?

Yes. The catback connects at the factory catalytic converter flange — no cutting, welding, or modification required. Bolt straight on with existing hardware.

Does this need to be painted or ceramic coated?

No. Stainless steel resists discoloration and corrosion on its own. You can install and drive without prep work or protective coating.

What's the sound level like compared to stock?

Catback systems typically provide a more pronounced exhaust note under acceleration while remaining civilized at cruise. Actual tone depends on your driving style — test-fit the system and listen before committing if possible.
