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

No. The catback bolts directly to your existing catalytic converter at the factory connection point — your cat stays in place.

What mounting hardware is included?

The system ships with all hangers and clamps needed for installation. Check the box contents before starting; you may need gasket material or sealant depending on your connection point condition.

Does this need to be painted or treated before installation?

Stainless steel arrives ready to bolt on — no painting or prep required. Over time, the polished surfaces may develop a natural patina or you can polish to keep it bright.
