RARE has the performance ones in stock for $550:

That's still less than a pair of headers.
Depending on your intended build manifolds are a nice option for a number of reasons.
Obviously, if you plan to lean more towards the performance side, the RARE manifolds would be a better choice.
You could sell the set you have to reduce the overall cost of replacements.
