Some related info from another thread

Yup. Many run those lines.

I thought the backs were for steam pockets .. not sure I like that

I am not sure if the back lines work or not I think they disturb the flow.
I read on another forum that Diamond Performance throw the pipes coming rear intake into the exhaust headers which it makes more sense .

has anyone tried this setup ?

Are you saying they use the rear intake manifold ports to dump the water and cool the exhaust?

Makes sense to me in one way although I’d think the header temps would be quite hot. Maybe not enough notice. Idk

Someone did it ? It works ?

I just run dumps on mine....from the rear of the intake where those are dumped overboard through the transom....helps keep the rear cylinder temps consistent and gets rid of steam pockets as Dan said.
