Some stainless steel headers don't offer enough back pressure, Motad for instance; and you need to sleeve them down at the collector point.
The Motad collector pipe measures 1364sqm whereas the original collector has an open area of 962sqm (based on a 2mm wall thickness) at its pinch point.
You can see where the original back pressure adjustment (pinch point) was made point on the standard header pipes collector point.
