Do I need new gaskets and bolts to install this?

The header bolts to your factory mounting points, but you'll want fresh gaskets between the head and header flange—old ones rarely seal twice. Fasteners aren't included, so grab stainless steel header bolts rated for your application.

Will this header fit with my stock exhaust system?

It connects at the factory collector location, so it plays nice with OEM and most aftermarket downpipes. If you're running a tight custom exhaust, test-fit before final installation to confirm clearance around heat shields and chassis.

Should I ceramic coat or paint this header?

Stainless doesn't rust, so coating is optional. Ceramic coating reduces underhood heat and gives a finished look, but it's not required for longevity. If you do coat it, let the header cure fully after installation before applying any finish.
