Do I need to ceramic coat or paint this manifold before installation?

Stainless steel won't rust, so coating is optional from a protection standpoint. Many builders ceramic coat for heat management and longevity under extreme boost—it's a performance choice, not a requirement.

Will this bolt directly to my stock turbo and intercooler setup?

It has a T4 flange, so it bolts to any T4-compatible turbo. Check your current turbo's inlet flange type before ordering—if you're running T3 or a different standard, you'll need an adapter.

What gaskets or hardware do I need for installation?

The manifold alone ships without exhaust gaskets or mounting hardware. Grab a quality stainless exhaust gasket set rated for turbo applications and use the fasteners appropriate for your engine bay setup.
