Major General
I would think a good many of the V-12s, but obviously an engine running at 18lbs boost (66-67in) of manifold pressure going into the cylinders is going to have higher pressure leaving the cylinders than an engine running at 40-44inches (5-7lb boost).
The only radials that I know of in WW II to use individual stacks were the R-2600s on some A-20s and B-25s. I could well have over looked some.
The later Zeros used paired stacks, 4 on one side and 3 on the other? WHich leads to difficulties on the top and bottom cylinders having much longer paths than the side cylinders. The FW 190 used side exhausts with most paired
but since 8 doesn't go into 14 evenly two cylinders had their own pipes? two cylinders shared two pipes?
F4Us used 6 exhaust pipes but the pre-4 had some rather long pipes.
and then
We can cover basics but when it comes to getting specific about any one installation/benefits it gets a lot harder as we are guessing at many things that they knew from measurements. By late in the war they were not designing exhaust systems by guessing or by what looked good or trying to fit it into space left over.
