So are you saying for the exhaust you want a megaphone or cone shape with
no bump or waist in the middle? In other words you don't want anything thats
like a venturi on the exhaust.
It looks to me like if you follow the angle and contours of the stock insert
and carry that onto the housing as you port you end up with the classic
D shaped exhaust port. Good idea ?
