Wow, the pipe routing between the 2 seems to be on your side for this conversion. aside from hanger position and where the pipe connects to the silencer it looks pretty much the same closer to the pipe hanger. The difference is bigger on the F30. This _should_ work without any hassle. Lift the car up, place the MPE right under the current exhaust and line it up to get a feel of where it will sit, where to cut and how to connect. Itīs semi-winging-it, but if the muffler shop aint shit it wonīt be any problem.
And it is definitely worth it, did mine 2.5 years ago and I never looked back!
Good luck
