That manifold is a BTB manifold.
Make sure the down pipes are supplied and they should have an X section.
Without these its not going to work as well as it should.

Kevin,
That manifold should be put up for sale properly where Alpina owners can see it. I know for a fact some people would pay an arm and a leg for it if you were to get it repaired.
They are shown to give upto 5 bhp gains. However, in this case its not about that - its a genuine Alpina item and there are Alpina owners with no manifolds.
Only one used BTB is for sale now - 345. Reason for sale - customer upgrading to newer BTB.
