Does this bolt to the factory catalytic converter?

Yes. This system connects at the cat converter and uses factory mounting points for the rear hangers, so you're looking at a straightforward bolt-on install with basic hand tools.

Will the rolled tips require polishing or sealing before installation?

The stainless tips ship polished and ready to install. No prep needed, though you can polish them again whenever you want to refresh the shine.

What if the exhaust doesn't fit my setup when it arrives?

Test-fit the system before final installation. If clearance or fitment becomes an issue, contact support with photos — don't force it or weld anything until you've confirmed the routing.
