Will this bolt directly to my factory catalytic converter?

Yes—this catback system is designed to bolt directly to the OEM cat converter. No adapters, cutting, or welding needed. Line it up with the mounting points and secure with the fasteners.

Do I need to remove anything else to install this?

You'll need to remove your stock exhaust from the cat back. Basic hand tools and jack stands are all you need. Expect about an hour of work if you're comfortable under a car.

Is the stainless steel finish ready to go, or does it need polishing?

The system ships ready to install. The stainless finish will naturally develop character over time as it oxidizes slightly—that's normal and part of the appeal. You can polish it whenever you want to restore shine.
