Sorry for the video quality gopro was acting up but the sound quality is all there and thats what you came for ! The m2 has MPE and m235i has m2 stock muffler and VRSF Downpipe The video doesn't do either their justice as they both sound better in person but you can hear them side by side same conditions and microphone
M2's MPE is $2000 +/-
M235i's M2 muffler and Catless downpipe cost about $400
Which do you think sounds better?!
