If all you really want from electric conversion is to get out of the garage and down the street , I will tell you to look elsewhere.
Maybe someone here knows better options out there.. There is not really much you can do other than maybe this hub motor setup link below . As your car is rwd, you can set this in your front wheels to make it “awd”. But this will probably be really expensive for what small task you want to accomplish and the added weight not very beneficial for your needs .
I for one, always hated exhaust sounds. But if loud exhaust is your thing, put on the stock muffler and install an exhaust cutout. Maybe check the BMW forums they might have a muffler that has valves that open up during harder acceleration but are quiet at startup and cruise .
