Not to dismiss your problem but even with my Stillen G3 intake I can hardly hear my intake. I'm a little surprised to hear that this is a problem. I suspect that your noise concerns would be better addressed by reducing road noise with the application of Dynamat or a similar product in the cargo/hatch/rear wheel well area. Much has been written on this topic and productive solutions are readily available.
Perhaps you could elaborate on your intake noise problem.
