99-00 Miata JDM Exhaust Manifold (BP5A-13-450B)

Called Mazda Comp on this part, they said it fits 99-00 JDM Mazda Miatas.

He guessed that it fit the Miatas without variable valve timing. This manifold doesn't have any EGR ports on it.

Its difficult to obtain more information than that, because we aren't really supposed to have it or be able to get it.
