My order has the MPE installed at the port so once I take delivery and break the car in I’ll give my opinion.
On a side note I saw a video from kiesmotorsports where they dyno a m340i with a stock exhaust then with a AWE exhaust and did 3 runs each and they found that with the AWE exhaust alone they gained 12 hp & 9lbs of torque to the wheels. Interesting from just an exhaust. My question is if anyone can confirm if the MPE adds power as well.

The MPE won't give any gains, it's just a muffler replacement basically. I am in love with the sound though.
