I would look at a set of bifurcated tublar exhaust manifolds. The Biurcated
exhaust is a exhaust which joins only two pipes at a time(The headers from a
Spitfire Mk II are of this type. Someone explained to me once that this type
of header has more even gas flow that the 4 into 1 collector you find on the
typical Spitifre aftermarket header. I have purchased the 4-1 header and
found that they do not fit with out a lot of "tweaking" . Rimmer brothers
sells this bifurcated manifold and they typically run about $190.00.
