Will this bolt up to my stock catalytic converter?

Yes. This catback starts at the cat and uses the factory connection point. Your existing converter stays in place—you're just replacing everything downstream.

Do I need new hangers or mounting hardware?

The system bolts to factory mounting points on your Mustang, so you'll use the existing hardware. No additional hangers or fasteners are needed for a straight install.

Can I install this myself?

Absolutely. This is a basic bolt-on—you'll need basic hand tools and a jack to get underneath. Plan on an afternoon if you're comfortable working under a car. If you're not, any shop can knock it out in under an hour.
