Do I need to remove the catalytic converter to install this?

No. This is a catback system—it bolts directly to the existing catalytic converter outlet. Your cat stays in place and emissions-compliant.

Will this system need welding during install?

Installation specifics aren't detailed in the product specs. Test-fit all connection points before committing to fasteners or clamps. Most catback systems use bolt-on flanges, but confirm fitment on your vehicle before purchase.

Does this come with mounting hardware and hangers?

The listing confirms only the catback exhaust assembly. Verify what fasteners and hangers you'll need by comparing the outlet flange to your factory setup before ordering.
