Will these headers bolt up without modifying my engine bay?

Yes. These mount at factory points — no grinding, drilling, or custom fabrication needed. Hand tools and basic mechanical ability are all you need.

Do these headers need painting or coating before install?

Stainless steel won't rust on its own, but some builders coat them for aesthetics or heat management. Apply any coating before installation to avoid overspray on finished surfaces.

What gaskets or hardware do I need to complete the install?

Header gaskets and fasteners are not included. You'll need fresh manifold gaskets, new studs or bolts, and potentially new gasket material for the collector-to-exhaust connection — get these before you start.
