I personaly have not tried, but i assume it would be a matter of having the down pipes for the exhaust modified to match, the manifold should bolt up ok to the engine, they wont bolt up to your current down pipes so from there its abit iffy with where the pipes go, whether they will be able to go past steering items and framework without been bent out of shape and negate the benifit of having the 560 manifold.

If u have the tri-ys and they dont work out i ll buy them from you, i have a Australian car 450SLC which is right-hand drive like euro cars and will work with the headers.

So, to answer your question, it will not be a straight bolt on modification and will cost you something like $300odd to get down pipes made to match everything up
