The berk midpipes don't bend as sharply (though they still have a pretty sharp bend in them), theoretically making them less restrictive. Also, there are 2 small resonators in each pipe, versus the one large resonator where the stock pipes meet. This makes the air going through less turbulent and be less restrictive overall. The exhaust would probably sound better because of less turbulence as well.
