Does this bolt directly to the factory catalytic converter?

Yes, this is designed as a catback system—it connects at the cat and runs to the rear. No fabrication or adapters needed for a stock converter.

Will I need clamps or new hardware to install this?

Basic hand tools and a jack are all you'll need. Check fit before final tightening—bring new clamps and hangers if originals are corroded.

Can I polish the tip or will it tarnish?

Stainless won't rust, but it can develop a dull oxide film over time. Light polishing keeps it bright—no special coating required.
