Ignoring all of the “x makes more on the dyno” and other variables or part numbers, is there any hard data/ measurements/ images saying there’s any difference between the EWG N55s exhaust manifolds or turbochargers? I’ve heard stories saying opposite things.


So talking about the exhaust itself, or power outputs because of other parts, or even power output in general isn't really relevant here. I agree those are the factors that make the m2 output more, but in regards to the turbo itself there isn't a difference.
