Its hard to say without real research/hard data. Air flow through the system is very complex, but my intuition is generally that a downpipe is worth doing - might not be but I routinely do it anyway lol. Most software squeezes out a bit more power with a DP, and I'm all in favor of reducing underhood temps which most of them help with, though they almost universally reduce CAT efficiency in the process (slower "light off"). I'm still waiting on getting an allocation for an M2, but am tempted by an used S7 - different class of car, but 600hp and 3.5sec or better 0-60 with chip and DPs pulling 1g in the corners sure is tempting!
