Although I didn't have my 550 dyno'd it felt like I had a lot more than 17whp. One reported F10 550i with Stage 2 are ran 12.9 @ 112.9 in the 1/4 mile. Considerably faster than stock. So the DINAN time must be doing something. I can personally attest that my car was considerably faster mid range and up.
35WHP? That's some serious gains from the downpipes.
But that's my experience
