Ok, so, justbti clarify I'm new with all this car talk and stuff so if I don't quite understand a reply, I apologise, I've recently bought a 2010, Audi A3 s line. im basically wondering what i can do to my car to make it sound great? I've read a few posts regarding a BOV and it seems a 007p and a split r are quite a common purchase? Which one would be best for me to get the nicest sound (the whoosh when letting off the pedal) I can without affecting performance or buggering my turbo up all together? 

Hi Josh...welcome to the Forum !

The one listed below is a typical Dump Valve set up...allows for better spooling and does make a great noise :-)

I'm sure other members have recommendations and personal preferences...anyone???
