Do I need to buy new mounting bolts or gaskets separately?

Bolts and gaskets are not included. Use OEM fasteners and a quality exhaust manifold gasket rated for stainless steel. Most builders source these separately to match their turbo kit spec.

Can I install this myself or does it need a shop?

Installation is straightforward if you're comfortable removing the factory manifold and unbolting the turbo. You'll need basic hand tools and a gasket scraper. If turbo work is new to you, having a second set of hands helps.

Does this manifold need ceramic coating or any prep before I bolt it on?

It ships ready to install—no paint or primer needed. Stainless won't rust bare, so you can run it as-is. Many builders apply high-temp ceramic or wrap for heat management, but that's optional based on your build goals.
