I used to be a DSMer but decided it was time for a change, hence why I am here I do put function before the sound, but having a BOV that sounds terrible will really get on your nerves (i.e. anything made by TurboXS). A stock 1G DSM BOV also makes a great economical choice for anyone with a turbo kit. They have a simple design, aren't obnoxious, and can handle up to 22-23 lbs/boost. Sorry for getting off-topic here.
