So is that turbulence cause by the gasses from the wastegate the important part? or is the seperation of the exhaust gas and the waste gas important?
If so, then wouldn't stock be better than the bellmouth, while the divorced be more efficient than stock?
This concern of mine postpone my decision on helix downpipe.
