Recirc DV obviously gets rid of this.
You can get dual DV's that are semi recirculating (Turbosmart I think do one) which lessens the problem a bit as you can set some to recirc and some to vent to atmosphere.
Before you fork out on a DV though, you could try my setup.
Leave the standard DV in place and simply remove the intake snorkel in the drivers side wing. This allows you to hear the standard recirculating DV. not very loud, but its a unique sound that you wont hear that much on scoobs.
you do hear turbo spool louder too which I think sounds cool.
also for the record, i;m running a very loud exhaust so the dump with the snorkel removed is loud enough to be heard, although I only realy hear it loudly when I give it some beans
