AA exhaust gen 2 vs. black series

[armenier]

Hello,
Wanted to reach out to you guys regarding some questions i have regarding an exhaust for an e92 m3 as i'm in the market for getting an exhaust and x pipe setup.

I noticed https://store.activeautowerke.com/co...nature-exhaust produces approximately 5 hp , however the black series exhaust on this site here: https://www.etektuning.com/i-3070225...e-exhaust.html claims to produce much more......have you guys dyno'd or experienced these two different versions (black series vs standard series) and seen a 7-10 hp difference between the two variants?

i find it difficult to believe that any exhaust , like the eisenmann black series or active autowerkes black series can produce 15hp vs a stock exhaust system on an e92 m3.


Best,

A catback will not gain any power. All those dynos are the typical tuner deceit by resetting adaptations. Buy an exhaust for the sound, not the gains

Same exhaust except the cans are powder coated in black.
