Will these headers fit my stock exhaust system?

These mount at factory connection points, but your existing exhaust pipe diameter and routing need to be compatible with the header outlet. Measure your system before installation to confirm fit.

Do I need to ceramic coat or paint these before bolting them on?

Stainless steel won't rust bare, so coating is optional. Some builders ceramic coat for underhood aesthetics or extra heat management — it's your choice, not a requirement.

What hardware is included for installation?

The header assembly ships complete. You'll need to confirm your engine block has factory threaded holes for the mounting bolts — a quick inspection before you order saves a headache.
