Mi16 Exhaust Manifold

[DRTDVL 4 1 Cars]

Hello everyone...

 

Please excuse me if this sounds loopy, which it might as i'm still wired on pain med's from a knee op today.

 

With the 8 exhaust port mi16 head, do most people just make a extractor to cover both ports per chamber or do they make them individual ports that merge later?

 

If it's 4 covering all 8 do they make it like a standard port where the two valve seat opening blend into a single port?

 

If not wouldn't that effect the performance of the flow into the exhaust manifold?

 

 

 

 

again sorry if it doesn't make sense - i feel like i'm floating at the moment.

Im unsure if it makes any diffrents tho
