Hi,
no it's not only for sound. It optimizes the air flow at higher rmps. As far as i understand this cooperates with vario cam system, because it works at 5.000 rpms plus. And it influences the air stream velocity. So this is not only a sound designing tool. And please note that the intake system is optimized with this part, and not without this part.
Please take a look at:

If you want to remove it, i would recommend to first complete your intake conversion and than do an A/B test with and without. Best would be with an A/B test on a dyno.
