Take the white doughnut out, cut the bottom silencer flush with the inside of the box and replace the very restrictive turbo to airbox hose that narrows down to 1 1/2" inside with another silencer. As for losing torque with an open intake here is a dyno which pretty much gives the same results as others I've seen with an open intake vs stock box.

Now granted, you need an open intake with a big turbo, but with the stock turbo it hurts torque.
