Hmm, they work on 900's but I don't think you'll get much gain on a 600. The restriction on airflow volume is the valve size, not the induction system. Ram air has most effect at high speed = high rpm and the 583s struggle to make power above 8500 rpm, regardless of how much fuel/air you chuck at them.
But if I'm wrong, I'll be first in the queue for a custom airbox!
