561HP BMW M5 E60 w/ Custom HMS Exhaust LOUD Sounds!! (1080p Full HD)

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! What’s your opinion on this M5 E60 by Mosselman and especially on its LOUD sound? Let us know in a comment! :)
