Hat man,
I have not come across this particular mod but there is a similar one very popular with road racer wanna bee's in Europe for the Opel Vectra.
This is called the "three pipe mod" and involves cutting the three resonator chambers from the air intake to achieve similar gains according to those opting to do it.
Sadly dyno tests found the torque , power and fuel economy all went DOWN and the noise went UP after this was carried out. The myth still remains however and the mod is still the hot item for Opel / Vauxhall conversation on those chatboards...along with neon lights under the car etc. etc.
Given the penny pinching nature of car builders it would not be there if it could be replaced by a straight piece of PVC tube from the Home Depot which delivers more power , economy torque AND a more impressive intake noise into the deal.
Your car and your call but I am dubious as you can probably tell.
Post here if you decide to do a test on it.
Peter.
