Will this bolt straight to my factory catalytic converter?

Yes. This catback design connects at the factory cat location using OEM mounting points — no drilling or welding required. You're connecting downstream from the cat, so your current converter stays in place.

Does this come with all the clamps and hangers I need to install it?

The assembly includes the main piping and outlet. Confirm your hardware kit matches your vehicle before final assembly — some installations may need additional clamps or support brackets depending on your exact setup.

Can I polish the burnt tip, or should I leave it as-is?

The burnt-blue finish is intentional and designed to resist heat discoloration. You can polish it down if you want raw stainless shine, but keep in mind the burnt tip will naturally darken again under heat. Most owners leave it as delivered.
