The MF system for the e92 328i is a better value than the AA for sure it’s probably $250 cheaper than buying the AA muffler and Mid Pipe which are sold separately. The MF also sounds really good in this video just not sure about power gains with it:
Edit:
According to this chart I found on Hotrod Magazine website the 2.5” is only good for like 250hp:
I also remember reading that 3” exhaust are good for up to about 330hp on another website. |
Meaningless and arbitrary.

Picture is unavailable, but according to Borla, the exhaust was worth 10whp:

Anyhow, anything for the E90 should fit the E92, but the there may need to be some trimming of the pipes.
Magnaflow and Borla mufflers both flow well, but the Magnaflow tend to be louder.
