Will this bolt up to my stock catalytic converter?

Yes. This is a catback system, meaning it connects directly behind the factory cat. No adapters or modifications needed.

Do I need to replace any gaskets or seals when installing this?

Test-fit the system first to confirm mounting condition. Have a fresh gasket set on hand in case the factory seals are worn or damaged during removal.

Can I return this if it doesn't fit?

Check fitment compatibility with your specific model year before ordering. Once installed, returns depend on the condition of the product and your account status — contact support with details if needed.
