I havent seen much of anything positive on the HR engine but some bad result but the VHR having either the PPE step header or the FI long tube did provide gain overall than OEM header + test pipe.
Personnaly, I always went back on the dyno after every mods and I did see myself gain on that aera.
OEM header + Test pipe VS Stillen header + Test pie VS PPE step header.
but again this depend also on how much everything else can actualy flow.
