Old manifold. This was on the car for a year and a half. Wrap and high temp paint sealed only. Lots of surface rust on the cast collectors, but there was still plenty of meat left. They will be cleaned up and should turn out fine as spares. Notice the crossover pipe has very little corrosion. Also notice how the interior is a dull grey instead of black indicating higher operating temperatures.
