Do I need new gaskets or hangers to install this?

Gaskets and mounting hardware are not included with this system. Grab new gaskets when you bolt it on—reusing old ones is a common leak source. You'll use factory hanger points, so check your existing rubber mounts before install.

Will this bolt straight to my stock turbo manifold?

Yes. This catback design is engineered to connect at the factory turbo outlet and bolt to the stock catalytic converter location. No modifications to the turbo setup needed.

Can I polish the burnt tips, or should I leave them as-is?

The burnt tips ship with that heat-blackened finish. You can polish them back to mirror finish with metal polish and a rag, or leave them dark—both look clean on the turbo. Your call.
