That is the question.
My M2 will be build soon (at the end of July - 30/07/2016) and I'm still wondering if I should order the MPE at $3,500 (CDN) or stay with the stock exhaust.
My M2 will be my daily driver 8 or 9 months a year so I don't want it to be too loud into the cabin.
I've watch lots of videos on Youtube recently featuring the stock exhaust and the MPE and so far I've found that the stock exhaust sound very nice but not loud enough. On the other hand, the MPE sound great in track mode (but too loud for a DD) but not in sport mode just like if the flaps were staying closed.
What a tough decision to take !
