Thanks Trevor, I look forward to see if anyone else replies, Inthink it might have been posted about before in another thread 

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?
