2g maniold porting question

[bob123131]

I have been porting 2g manifolds on the side for awhile now and not only do i take away the step i cut out the center part that splits the 4 runners(I know they arnt technically runners but dont know what to call them on a ex. mani). Anywase i recently got my hands on an evo 3 gt mani and an old sbr one and the area i cut is still there. Have i in someone way decreased the flow by not making it a smooth transition from 4 to 1? If not how come performance companies put this in. In the vfaq it appears he has done the same, but doesnt say it anywhere.

If you live in Twin cities and i ported your mani and im wrong my bad pm me and i will make it up to u somehow.

Yea you need to leave that in. It keeps the flows from running into each other, makes for a smoother transition.
