Better picture of the exhaust and intake manifolds.
Why three exhaust pipes? Yes I know there are
exhaust ports in the center housing.
I guess it is cheaper to make than four pipes.

Paul,
I don't think it is cheaper, it certainly doesn't look cheaper !
Many motorbikes have double pipes, mainly used as a heat shield.
Perhaps this is the reason here ?
I guessing from the photo's it's a one piece flange, perhaps the heat shield
helps to minimize heat fluctuations, and the possibility of cracking.
The extra meat would add some strength also.
Just a thought, may be completely wrong.

I know what the outer shell is for. Keeps the pipe hot so the cat
starts working earlier.
