Do I need gaskets and fasteners to install this?

The header assembly ships without gaskets or mounting hardware. You'll need header gaskets and stainless fasteners rated for your engine's bolt pattern — grab those separately before install day.

Will this header work with my existing exhaust setup?

Top-mount configuration is typical for jet boat applications with integrated pump discharge. Verify your current exhaust piping aligns with this header's outlet before committing. You may need adapters or new piping depending on your exhaust routing.

Does stainless steel need any prep before installation?

Stainless arrives ready to bolt on — no painting or coating needed. Clean the mounting surfaces on your engine block with a wire brush to ensure proper gasket sealing, then torque to spec per your engine manual.
