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.
