561HP BMW M5 E60 w/ Custom HMS Exhaust LOUD Sounds!!
This is without a doubt one of the best sounding M5's we have ever heard! This BMW M5 E60 has a Mosselman Performance Package which basically means its faster, louder and more powerful! Mosselman added 54HP (Stock 507HP) and 56Nm (Stock 520Nm) to the car and we think they did a great job!
