DesignTec Valvetronic exhaust replacement for PSE

I had the Top Gear switchable back boxes fitted to my Targa last year to replace the original PSEs. There is a drone between 2-3000 revs which reverberates in the cabin. If Im quicker on the throttle its much better...
 
@JD Torino
re: your comment about the switchable topgear system droning between 2-3k, is this in quiet or sport mode? & does switching make much difference to the droning?

I ask as mine has the non switchable version, which I quite like, apart from the drone at motorway speeds, so was considering changing to switchable at some point.

Hi JD - is this the case both in quiet and loud mode? Also, is it generally very loud at low revs even in quiet?

thanks
james
