After watching the Mine's R34 GT-R videos on youtube, I can't help but think that what I think is the BOV/BPV (I'm not sure what they employ) sound is amazing. I think it's also used on the GT-R Z-Tune. Does anybody know what it is, and if you can make an Evo sound like that?

One of the videos is here, go to about 1:40 where they start testing...

Mods, if this belongs in the other cars section, please move it over there. Thanks
