Thats weird...can anyone explain?
Im bored so was cruising ebay looking at stuff when I found this :
LINKY
Now, my question is...why have they linked Cyl 1-4 and 2-3 rather than just taking all of them straight down into a single collector?..
Random question, but im intreagued..

You need to read up on manifold design!!!
You use cross pulsing from the "opposing" cylinder in cycle terms to create a depression to extract from the other cylinder. This effect
is magnified with a smaller cross section of pipe linked.
Its actually extremely complex in detail but simple in principle when you know the "ball-park rules" of what works and what does not.
There is a very good book on the subject called "4 stroke engine tuning" but I can't remember who wrote it, but it goes into all you
need to know on exhaust manifold design.

Have a look at the R V8 factory manifolds - on left side 1/5 and 3/7 linked, on offside 2/4 and 6/8.
