Default Re: Best exhaust for M3?

On my E92 I have:
OEM headers, ESS HFC Xpipe, Evolve Valvetronic catback. Everyone that rides that car is impressed with how loud it can be when stepping on it yet it has zero drone over 2k rpm. Zero.

Interestingly, when I had an oem Xpipe and the ACM oem exhaust mod it wasn't loud but there was drone right at 3k which is a killer for highway trips. After switching to the ESS HFC xpipe it magically moved the drone to 2k and made the exhaust much louder

On my E90 I have yet to install:
BW stepped headers, BW HFC Xpipe, BW street catback
