Just be aware, before you start ripping off resonators that their primary purpose is to improve air intake flow by removing harmonic pressure waves in the intake that bounce back from closing valves, well at least in NA engines. The side effect is to quiet the intake down too but that's because the air flow is smoother and more even.
See here:

The author tried replacing his stock, "restrictive" intake and resonator with a bigger PVC pipe job and lost power, but gained noise.
It's all a bit counter-intuitive but there is real science behind this sort of stuff!
With a turbo, I'm not sure it's so critical owing to the longer intake path and positive boost up the rpms where you make power but you have to wonder at the purpose of the "milk bottle" inside the air box entrance.
