Does this manifold need any prep before bolting on?

Inspect the mounting flange and collector outlet for any manufacturing debris, then clean with a wire brush. The stainless steel is ready to install as-is — no additional coating or finishing required.

What hardware do I need to mount this?

Mounting hardware is not included with this manifold. You'll need stainless or high-temp fasteners rated for turbo manifold applications — your B-series engine's service manual will specify the correct bolt size and torque spec for head mounting.

Will this work with my factory exhaust or turbo setup?

This is a manifold only — you'll need to verify your turbo inlet diameter matches the collector outlet and that your exhaust piping downstream is compatible. Test-fit before finalizing any permanent connections.
