Will this bolt directly to my factory catalytic converter?

Yes. This catback design connects at the existing cat outlet — no modification needed. Use the factory mounting points and hangers for a clean install.

Do I need to remove or replace the catalytic converter?

No. Catback systems start downstream of the cat. Your factory converter stays in place and bolts to the inlet of this system.

Will stainless steel rust or need any prep before install?

Stainless resists corrosion naturally — no paint or coating needed. Once bolted on, it's good to go. Regular washing keeps it looking fresh.
