Will this bolt directly to my stock downpipe?

Yes — this is a catback system designed to connect at the factory catalytic converter outlet. Your downpipe stays in place. You're only replacing the midpipe, resonator, and muffler section.

Do I need to remove anything else to install this?

You'll need to disconnect the rear O2 sensor (if equipped), unbolt the stock system, and bolt this one in. Expect to spend an hour with basic hand tools. Jack stands required for undercar access.

Can I drive this without heat-wrapping or ceramic coating?

Stainless steel runs cooler than aluminized steel and resists discoloration naturally. No coating is required for function or durability. Heat management depends on your intake and underbody setup — test-drive to assess cabin heat before adding wrapping.
