Your pretty much out of luck.
On typical front engine cars, people add resonators to get rid of drone.
(looks like a glass pack, ex. you'll see 2" piping bulge out into a 12" section of 3" piping then back down to 2" piping. possibly multiple shorter resonators.)
They act like mini mufflers.
On a Boxster, you just don't have the space to add a few of these.
