As for performance gains, not noticeable but there probably is some up to 5whp

Any new vids would be appreciated since there aren't many out there anyways. It seems that this f30 performance exhaust is not in high demand compared to the e90 performance exhaust.
I was told that the sound is very comparable to the e90 perf exhaust but I have my doubts since a 4 banger will never sound like a smooth 6.
