+1. If you want minimal sound then stock is probably best. Stock is a true cold air intake, so you have the benefit of the colder air. I like the swoosh sound of the BMS hot air intake and I think there are some small gains due to les retriction.
Maybe adding some air scoops to the stock setup would give some small gain.
