Thanks.
I'll look into it. One of the exhaust shops here in Brisbane is pretty confident that some J pipes will sort the drone out. They've got some experience with a few GTSs now and think they have it nailed.

Manual here too but the drone is very bad. Seems to hit the boot and cabin resonant frequencies at around 1000-2200rpm, i.e. drone is always there, even at idle! Not good.
