Do I need gaskets or hardware to install this?

Check your existing connection points before ordering. Most catback systems reuse factory gaskets, but having a fresh set on hand prevents leaks at the cat-to-pipe joint. Test-fit the system to confirm what you'll need.

Will this work with a stock catalytic converter?

Yes. This is a catback system, meaning it connects downstream of the cat. Your stock converter bolts right up to the inlet pipe.

What's the return window if it doesn't fit?
