Will this bolt directly to my factory cat, or do I need an adapter?

This mounts at the factory catalytic converter outlet. Confirm the outlet diameter matches before ordering—if it does, you bolt straight on with no adapter needed.

What hardware comes with this exhaust?

The catback assembly ships as one unit. Mounting hardware is not specified in the product details—check with support to confirm what fasteners are included before installation.

Is the tip ready to install, or does it need polishing?

The tip arrives polished and ready to bolt on. No finishing work needed out of the box.
