Just rip all that stuff out and put a K&N in there. The engineers at Porsche don't know how to make a car sound good. Right?
...or is there physics involved? I read about this stuff once and had a basic understanding, maybe you can too.
Pressure waves, harmonics, volume, length, clean flow vs disturbed, ... Way too much engineering involved for me to think I could make it better with a little sheet metal, some PVC, and a generic filter system.
