Do I need to remove the factory catalytic converter?

No. This catback system connects directly downstream of your factory cat. You're only swapping out everything from the cat back—the factory converter stays in place.

What hardware do I need to bolt this on?

Mounting hardware at the factory connection points is included. You'll need basic hand tools—wrench set, jack, and jack stands. No welding equipment required.

Will the stainless steel require any prep or coating before installation?

No prep needed. The stainless steel is ready to install straight out of the box. If you want a polished finish over time, you can detail it—but the base material comes factory-ready.
