Morning all

Following on from my 360 or 430 thread I have seen a 430 that I quite like. However the manifolds appear to be original and there is no reference to them in the full and documented service history.
The car is a 2006 with 22,000 miles on the clock.

So my questions are. Were the manifolds a factory recall and what are the repercussions of buying a car with the original manifolds on.
