Will this bolt directly to my stock catalytic converter?

Yes. This system connects at the cat with factory bolt-up points — no custom fabrication needed. You'll want to inspect your cat outlet diameter before ordering to confirm fit.

Do I need to remove or modify the stock resonator?

Stock resonator removal is typically required for catback installation. Check your service manual or test-fit first to confirm what needs to come off on your specific car.

What about hanging hardware and clamps?

Confirm what's included in your shipment before installation. You may need OEM hangers or aftermarket band clamps to secure the system — have spares on hand in case any are damaged during removal of the old exhaust.
