Go Plumb back aka recirculated such as this
2008+ WRX Racing Bypass Valve - TurboXS
or
a hybrid one such as this
WRX/STI Hybrid Valve - TurboXS
With the racing one you will get a much more pronounced swoosh blow off sound and won't lose any performance or sound ridiculous when driving by in the city.
The hybrid one will give you the
bov fart sound of the atmospheric while recirculating it and won't lose performance either.
If it was me I would keep my stock
bov and spend the dollars on something more useful, unless planning to run 30pnd of boost (lol) or want to be part of the
bov fart crew.
