Owners of the Dolomite 1500 model will be acutely aware of the problem with the exhaust manifold to downpipe gasket blowing at frequent intervals. Spitfire 1500 owners have the option of curing this permanently by using an all in one downpipe/extractor manifold which doesn't have that joint. Unfortunately Spitfire manifolds won't fit the Dolomite and so the only option is to make do with the original set up, albeit making sure that the mating faces of the manifold and downpipe are filed perfectly flat, nuts and bolts used instead of studs/nuts, chewing gum, or bits of string are used to hold the two assemblies together. The added bonus with extractor manifolds is that they do release a bit more BHP, especially when used with a less restrictive exhaust.
